[Lucid] request pull Bug# 507148 Radeon Mobility 7500

upstream suggested that we backport patches from 2.6.33, to get radeon 
work with KMS. After discussion with apw, I understand that we are ok if 
KMS+radeon is not supported on some of the older cards. I have picked a 
few of the patches that jdstrand and marc Deslauriers have tested for me. 
These patches enable them to get X working, but they are still seeing 
crashes of compiz after an delay, ie happens slower than before. But, 
atleast they have had some success with this kernel.

I am submitting these patches for review & pull to Lucid.

While I was at this I noticed a patch that fixed a security hole, issue 
which can allow user to abuse drm on r6xx/r7xx hw to access any system ram 
memory. I will pick this patch and submit to lucid as well.
