Subject: [PATCH 03/12] drm: rework radeon memory map (radeon 1.23)

This code reworks the radeon memory map so it works better
for newer r300 chips and for a lot of older PCI chips.

It really requires a new X driver in order to take advantage of this code.

Subject: [PATCH 05/12] drm: rationalise some pci ids

This is the start of some work from Roland Scheidegger to align
the X DDX pci ids and the drm ones, however we don't want to put
r300 ids in the kernel just yet, they destabilise a few machines.

Subject: [PATCH 07/12] drm:  remove pointless checks in radeon_state

If these were valid checks, we'd have already oopsed several
lines above where we were already dereferencing them.

DA: these used to be valid but other changes made them unnecessary.

This adds all the r300 and r400 PCI ids from DRM CVS, it also
makes these cards only initialise when the new xorg driver is
used, as otherwise the DRM can cause lockups.
