Same here. I already reported the problem, and a possible fix to it, a long
time ago: http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=34759

I have a different board rev., otherwise exactly the same (24bit Newport):
newport0 at gio0: SGI NG1 (board revision 5, cmap revision 5, xmap revision 5, 
vc2 revision 0), depth 8

And I also need offset 29!

Great! Works fine for me.

I saw that you applied exactly the same patch to gio/newport.c which I
suggested in my PR #34759! :)
