 Unfortunately the tests of Comment #14 were not significant. I have tested the
patches with the same kernel but a different Xorg namely
xorg-x11-server-7.6_1.9.3-122.1 and xorg-x11-driver-video-7.6-180.1 which
however now does resolve UMS for radeon so that everything does again work
without any patch and kernel option.
 With a full KMS kernel like 2.6.38-0.0.12 on the other hand unfortunately
video mode initializtion does at me currently not work at all under any
configuration: neither with the integrated monitor nor with my external one
over any of the ports DVI, HDMI or VGA. Here are the exact results:

VGA: itg: colored vertical lines; ext: c.v.l.(the same), mouse: pixelry
HDMI: itg & ext: colored lines; this time brighter with more white, mouse: same
DVI: itg: 1st: colored lines; 2nd: sparse colored lines ahead of white bg,
     ext 1&2: at first 'no signal'-dark then the same as for itg, mouse: same

 As the screen output for DVI has differed between two consecutive test runs I
presume that there is no substantial difference in the result between different
monitors and ports (always vertical colorful lines). The mouse did at first
never appear until you moved it into the upper left screen area where there
would normally appear an xterm by xinit. From then on the mouse pointer was
represented by a rectangular pixel surrogate. Rebooting was the only escape
though the system was still reactive (no crash or hang): changing the virtual
terminal (chvt) or exiting X from an exit typed into xterm both resulted in a
fully blackened screen with no more output.
