Now testing 2.6.36 + your v2 patch. Three reboots all is well so far - I do not
expect any surprises, since mem mapping seems to be the same:

martin at shambhala:~> dmesg | grep "radeon" | egrep -i "(gtt|vram)"
radeon 0000:01:00.0: GTT: 256M 0xD0000000 - 0xDFFFFFFF
radeon 0000:01:00.0: VRAM: 64M 0x00000000 - 0x03FFFFFF (64M used)
[drm] radeon: 64M of VRAM memory ready
[drm] radeon: 256M of GTT memory ready.

I also tried to setup Radeon KMS DRM on my Dell Dimension 5100 at work, but I
found quite some issues - ttys are blank after KMS switch, machine locks with a
backtrace on enabling XRANDR for 1680x1050 + 1280x1024 or so, seemed to be a
memory issue. 32-Bit, almost 4GB of RAM (no PAE). I hope to be able to try on
this workstation in November again and to report some bugs.
