Yes, but only the Coral-P, and X11 only correctly using a modified X
server (xfree86 and xorg).

The problem is the endianess. The Coral-P does not contain a byte
swapper for the video memory, so it cannot be easily be used with a
big endian CPU like many other grafik chips. Even the successor of the
Coral-P has such a byte swapper.

Our modifications to support Z-images are done in the non-accelerated
driver in the shadow frame buffer extension.

The Coral-P accelerated driver wasn't very stable when we tested it a
while ago, I assume this very much depends on the functions you use.
