We used to limit the rs4xx gart aperture to 32 MB, but I suspect
that was due to not meeting the alignment requirements of the
aperture. This patch should only be applied after:
"drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics"
has been applied.
This patch should probably soak for a bit in d-r-t.

The "error" variable is unsigned so it's never less than zero. I
changed it to check if (freq < current_freq) directly.
"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative. Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.
Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.
This allows kexec to work on a Power6/RN50 system.

We cannot the initial configuration set by the BIOS not to have a dither
mode enabled which conflicts with our enabling the Spatial Temporal 1
dither mode for PCH. In particular, the BIOS may either enable temporal
dithering or the Spatial Temporal 2 with the result that we enable pure
