I'm planning on getting x86emu support into vbetool in the near future, mostly because AMD64 doesn't have vm86 support. It's worth noting that attempting to re-POST many (most?) laptops will fail miserably - the code simply isn't available after boot. Saving/restoring state with VBE code tends to be more reliable, but there are some machines that need POSTing.
In the long run, it's the sort of thing that needs a hardware database, which effectively requires it to be in userspace. -- Matthew Garrett | mjg59@srcf.ucam.org
