I just bought a bunch of nvidia pcie cards, installed the nvidia kernel
crap, setup my xorg file and everything worked out of the box. But this
was not my goal, I wanted an complete free software based multi seat
system working with packages out of main repository. But it seems an
regression in design and some bugs make multi gpu setups very
troublesome. I have posted logs and configurations on the radeonhd
mailing list with my issues. But some developers have stated multi gpu
is not an priority...
