Sparcbook X working again

[Julian Coleman <jdc%coris.org.uk@localhost>]

Hi all,

I've recently updated the Xorg pnozz module to work with current Xorg.  This
means that it's possible to use X again on the Tadpole Sparcbook.  There is
still a bug with using the chip's acceleration features that I need to track
down, so it's using unaccelerated operations, but it seems otherwise fine.

Regards,

Julian
