yes, i had one that did this as its first thing then chained into some
other bios call.
i have to look... i might still have the trace log.
i do no attempt in detecting bad stuff. its perfectly valid to enable
interrupts in the emulator... there are no interrupts in the virtual
machine right now (might change if i implement pit timer).
the list is just the stuff that was tested with the emulation
and worked enableing video.
might be a good idea to add "aggressive" bios behaviour in the
description.

have you caught any bioses reenabling interrupts or doing other things
like that?
what's the strategy for detecting vesa bios "doing bad things"?
is the included list of video cards a list of cards that do not work with
the regular realmode but do work with emulated real mode?
