Yes. Is this a report of observed failure? And how would VMWare even
go about implementing this kind of misfeature? Maybe it fails with

It supposedly is.
You mean "is a real failure"? Or "is triggered by particular
instructions"? It seems profoundly bogus (as in, surely DOS or
something reads the framebuffer).
Maintain a shadow framebuffer, and copy it to the real framebuffer on
update...
How would you populate the shadow framebuffer? Pass it in from real mode?
Erm. BIOS always says basically the same stuff, so just compile a
screenshot into the setup code?
