Here's what I had written:
http://www.freedesktop.org/~anholt/trident-1.tar.gz

Nothing comes on screen because it gets stuck in idle.  The read from
the status register is giving me 0xffffffff, suggesting to me that I've
got the address wrong or the mmio is not being set up.  I just put the
inb/outb stuff in DrawInit in today trying to get the mmio enabled, but
no luck.
