The POWER4 parts are just noise in our case; what broke the mirroring
is the changes made to check_display, where each available display is
opened. (as said in private mail already)

I don't think so, but I'm no expert.

There's no support at all currently, only a gross hack to set up a
basic mirroring between the 2 heads. BenH told me that looking at the
XFree86 radeon driver might help to get something done on the M3.
