There was a thread on acpi-devel about POSTing VGA ROM after resume:
http://marc.theaimsgroup.com/?l=acpi4linux&m=109023076427394&w=2
The code does a real mode switch in kernel and execute the ROM. Ok, doing
that in userspace is more elegant, but that code is not a mess (though
it's arch dependant).
Btw, how do we POST non-x86 (eg. ppc) video boards? I don't think that
there's x86 code in their ROM...

sysfs? I sent a patch a while ago but didn't get much feedback.

sisfb has a memory manager for fb/drm, it may be worth a closer look.
