Neither NetBSD or XFree86 can (currently) change the refresh rate on any
ffb or afb graphics card so this has to be done by OBP.
Unfortunately there's very little information about these cards
available and the OpenSolaris source doesn't contain anything useful
about them. Have a look at the forth words defined by the card's
firmware, maybe it's not r1280x1024x85 but something slightly different.
My Creator3D only offers 1280x1024x76 for instance.=20

have fun
Michael
