Gabucino asked to limit DOCS write to him.

is it possible to enable TVout using VESA bios calls?
dosemu and some other projects has code for handle VESA calls from linux.
I also used them in dosrunner.
They run small program (actually it's a gate between your program and
DOS/bios), catching exceptions (privileged port access etc) and emulate them
if allowes (if port range is ok, do port r/w emulating the problematic
instructions else skip them). There is also a handy library (called LRMI)
for this. Of course, it requires root.
