Xorg can't enable drm anymore with the new kernel, which disables about any hardware accelled rendering.dmesg show me a error about ioremap

Code:

#dmesg |grep drm
[ 741.797152] [drm:radeon_do_init_cp] *ERROR* could not find ioremap agp
regions!

If I downgrade kernel < 2.6.29,this problem is disappered.

More information about this problem ,please see the bugs I reported at bus.freedesktop.org
