You might want to poke at sys/arch/sgimips/gio/newport.c, around line 510.
The code matches the SGI docco very closely, but perhaps we missed something.

(I've put the relevent docs up at http://www.rezrov.net/docs/)

Seeing as how it's just a single bit error, perhaps we need to wait for a busy
bit to clear in rex3_read().  That could explain why colormaps are sometimes
screwed up ...
