Bug#390172: Bug still exists in 1.1.1-17

[Matthew Wakeling <matthew@wakeling.homeip.net>]

Update:

I inserted a log statement before hw/xfree86/x86emu/decode.c:122 to just 
print on the stderr that it was emulating an instruction at a certain 
address. The result of running that was that I got a 500MB log file in 
seconds, with it executing instructions all over the BIOS. I had 12 
million log statements, executing 4214 unique addresses. The most popular 
addresses were executed half a million times each.

I thought these BIOSes were meant to just display a quick status message 
on the monitor and then poke a few values here and there into memory. 
Sounds like something is running away big time.

I can confirm that the graphics card works fine in dual-head with a 32-bit 
processor, so I don't think it is the BIOS itself that is stuffing it up.

Any further ideas?

Matthew
