I can get X's r128_drv/UseFB driver to work with /dev/fb0, but attempting
to use anything other than X's fbdev with /dev/fb1 sig-11's (it seems to
be the same no matter what driver /dev/fb0 is using).

This actually happens on both /dev/fb0 and /dev/fb1 when X's fbdev driver
is used. It seems that it often just forgets to copy its shadow framebuffer
to the real framebuffer. Setting ShadowFB to false, seemed to fix that.
PS An XF86Config-4 and XFree86.0.log from when I tried to use fbdev on /dev/fb0
and r128 on /dev/fb1 is at http://www.ics.uci.edu/~jronne/tmp
