something got merged yesterday (not yet in the fedora kernel until
I rebase), that changed a lot of this.

drm: add new radeon PCI ids..

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.
============================================

relevant bit being..

+       /* if we require new memory map but we don't have it fail */
+       if ((dev_priv->flags & CHIP_NEW_MEMMAP) && !dev_priv->new_memmap)
+       {
+               DRM_ERROR("Cannot initialise DRM on this card\nThis card
+requires a new X.org DDX\n");
+               radeon_do_cleanup_cp(dev);
+               return DRM_ERR(EINVAL);
+       }

I'll drop the cripple-radeon patch today, and we'll see what happens.
