Ok. You're doing better than me - with this iBook I'm using, trying to
start MoL with console video enabled totally wacks the framebuffer out.

Because MacOS (or MoL, I'm still not 100% sure) has no concept of pixel
formats that have bitfields of different widths for different colors. You
can run X in 15bpp, and MoL will work fine in 15bpp (but if you're using
DRI, that won't work, it has to be 16bpp). You can run X in 24bpp, and run
MoL in 24bpp, and that will work. But with X in 16bpp, you won't be able
to get non-palletized graphics in X with MoL. That's just how it is. (So
far. If you can hack it to make it do the right thing, I encourage you to
do so.)
