that patch only implements vgaaccess in the r128 driver.  for dualhead
you'll need to apply the patch in but 1760 as well.  I'm planning to
post an updated r128 dualhead patch soon. the 'entity in use' error is
because the driver you are using is not dualhead aware.  the patch in
2089 should allow you to use single head without usefbdev.

David Stanaway put together a combo patch against 6.8.1 here:
http://sprocket.stanaway.net/~david/xorg/
that works for him on ppc.  you might give that a try.

just run 'make' in the ati directory and copy the resulting r128_drv.o
to your x installation.
