exscroll and the test program behave perfectly. exscroll will first
try to set a Mode-X screen, and if that fails, it uses GFX_AUTODETECT.
The test program uses #ifdef's to be able to compare the driver ID,
then if that's true do some Mode-X specific stuff. Since the "extra"
code will only do anything if you're using the Mode-X driver, the mere
presence of the define changes nothing.
However, I just now did try compiling with --disable-vga and there was
a linking problem with test. Undefined reference to
split_modex_screen. So, I can either make it so the Mode-X functions
are exposed if GFX_MODEX is ever available (regardless if it's
settable, or I can change the test (and probably exscroll) to check
for GFX_HAS_MODEX instead. I'd prefer to do the former since I don't
think the GFX_HAS_* macros should be exposed to the API (since VGA,
ModeX, and VBEAF are the only drivers to have them).
