I know. The NetBSD-specific code needs to open more than one device,
right now it tries to mmap() everything through a single file descriptor
which isn't going to work. There's a workaround ( /dev/xf86 ) somewhere
but that's more or less i386-specific and rather ugly.

Definitely.

There's no way for the ati driver to simply ignore adaptors it cannot
mmap?

have fun
