g400 framebuffer-update

[Aaron Solochek <aarons@andrew.cmu.edu>]

Apparently, my g400max, with kernel 2.2.14, doesn't like videomodes over
8bit color.  The computer boots with whatever video mode I want, but
will not sync if the color depth is greater than 8 bits.  I can drive
the monitor at 1600x1200 no problem, also at 1024 I have it set to use
100mhz mode, also no problem.  

One quick question though, my cursor is currently a big (3x3 characters)
black box.  How can I fix that?  Is is a hardware/software cursor
issue?
