This patch allows you select different modes on a Mac. The functionality
was there but not taken advantage of. This is needed because the resolution
can be 834x628 on a Mac and the screen is really screwed up with more than
8 bit in that case.

This patch forces 1024x768-60 modes on PowerBook Lombard and
Mainstreet. No need to pass vmode:14 anymore.

That one is wrong. The machine type must be probed differently. Also, some
wallstreet's have a different screen (passive matrix) which is 800x600. I'm
trying to find a way to probe for it and will come up with a patch for this
In the meantime, passing the vmode is the correct solution.
Ben.
