But they aren't disabled either. If the cache is turned on by the PROM,
it remains on. This seems to happen on my SS4. Cache-aliasing is not
yet handled, but problems because of this don't show up often because
the caches are relatively small. This will be fixed shortly in post-1.2.

A minimal tcx driver will be in post-1.2. The X server will be able to
use it in `cgthree' mode.
