Okay, it shouldn't do that, so we'll have to look into why that's
occuring.  In the mean time, add an option "ForcePCIMode" to your
XF86Config file (in the Rage 128 device section).  That should do the
trick.

Yep, it sure is.  Worked long and hard to fix the problems with the Rage
128 Pro support :-)  Again, we'll have to look into why that's occuring.
