I'd use GFX_AUTODETECT, because then your program will work on machines
that don't support VBE 2.0 as well as ones that do. Also, it would be a
good idea to check the return value from set_gfx_mode(), because SVGA
resolutions aren't always available and the function may fail.

That doesn't explain your problem, though. Can you post some source that
demonstrates the trouble? I need more info before I can say what's
wrong...
