Do you mean to say that the console driver knows how to manipulate
the display hardware to use 2 and 4 bit modes?  When does it do
that? (I've only started using the intvid console, as Takashi just
made available his fix for the PB180 -- amazing what that guy can
do using MacsBug... I think it'd drive me crazy trying to reverse
engineer code as he has).  I've only seen the console use 1-bit video.

Again, do the X11 server and dt control the video display depth via
system calls, or do they open a file in /dev and send it video parameters,
or do they have their own drivers, and just map in the video control
registers?
