Ivar sounds like he might know more about it than the people who keep saying the radio would be the last thing to go in a fire.

In an electrical jet like the B777 systems are designed for redundancy.
With my experience and knowledge of the B777 systems the flight control systems would probably last longest in case of a fire.
As long as there's no structural damage to the fuselage.
But every emergency is different, so that's just an educated Guess.

If this was MH370, and it was on fire, what are the chances it could fly for hours more until fuel exhaustion? A single engine fire that goes out?

I don't believe this for a second. Just more obfuscation.
If there was a plane on fire a MAYDAY would have been broadcast.
One last things that I forgot to mention, which actually likely is the most important point of them all, is that the transponder was actually turned off about 5 or so minutes BEFORE the pilot communicated with ATC
At 01:19:24 MYT LUMPUR RADAR at KLATCC instructed MH370 to contact HO CHI MINH Air Traffic Control Centre (HCMATCC) on radio frequency 120.9 MHz. MH 370 acknowledged with “good night Malaysian Three Seven Zero”.
At 01:21:04 MYT, MH370 was observed on the radar screen at KLATCC as it passed over waypoint IGARI. At 01:21:13 MYT the radar label for MH 370 disappeared from the radar screen at LUMPUR RADAR KLATCC.
Even though that airworthiness directive doesn't apply, I haven't ruled out the possibility that they might issue a another one to encompass other models of the 777, or expand the existing directive to the other models.
American transport officials warned of a potential weak spot in Boeing 777s which could lead to the "loss of structural integrity of the aircraft" four months before the disappearance of Malaysia airlines Flight MH370.
The Federal Aviation Administration in Washington drew up an Airworthiness Directive in November. It was triggered by reports of cracking in the fuselage skin underneath a Boeing aircraft's satellite antennae.
In its directive the FAA, which is responsible for supervising the safety of American-made aircraft such as Boeing, told airlines to look out for corrosion under the fuselage skin.
This, the FAA said, could lead to a situation where the fuselage was compromised leading to possible rapid decompression as well as the plane breaking up.
"We received a report of cracking and corrosion in the fuselage skin underneath the SATCOM antenna adapter," the FAA warned. "During a maintenance planning data inspection, one operator reported a 16-inch crack under the 3-bay SATCOM antenna adapter plate in the crown skin of the fuselage on an aeroplane that was 14 years old with approximately 14,000 total flight cycles.
"Subsequent to this crack finding, the same operator inspected 42 other aeroplanes that are between 6 and 16 years old and found some local corrosion, but no other cracking. Cracking and corrosion in the fuselage skin, if not corrected, could lead to rapid decompression and loss of structural integrity of the aeroplane."
The FAA directive in November called for additional checks to be incorporated into the routine maintenance schedule of the worldwide 777 Boeing fleet.
Unless the fire had already disabled the radio before he knew there was a fire, or before he had a chance to report it, or he was more busy reacting to the fire so that communication was a secondary priority.

If these systems were disabled by a fire, undoubtedly the pilot would have communicated so, rather than a nonchalant "MAH 370, goodnight."
