Does anyone have an opinion on the usefulness and stability of the i386
"Biosacall" routine, for accessing the VESA interrupt calls (int10 fn 4FXX)?

I need access to those VESA functions that don't have protected mode entry points,
from within my video driver, in a non X-window environment.  Obviously I'm talking
about an i386 install here.

I want to keep this as simple as possible, so I'd prefer to avoid the use of an
x86emu style emulator.  I'm not sure I could implement such a thing in a kernel
driver anyway.

If anyone has any experience dealing with bioscall, I'd like to hear about any
problems you may have run into.
