[945GM] X fail to start on kernel 2.6.28

mesa intel-2008-q4 branch
X failed to start and print following kernel message
[drm:i915_irq_emit] *ERROR* i915_irq_emit called without lock held, held 0 owner 00000000 de8de9c0
After bisect, below commit cause the problem, revert it could fix the issue. It is strange that my kernel config has "CONFIG_HIGHMEM64G=y", and GEM works with this option.

drm/i915: GEM on PAE has problems - disable it for now.
On PAE systems, GEM allocates pages using shmem, and passes these
pages to be bound into AGP, however the AGP interfaces + the x86
set_memory interfaces all take unsigned long not dma_addr_t.
The initial fix for this was a mess, so we need to do this correctly
I found the same problem that Li Peng in Gentoo with the following versions:
gentoo-sources-2.6.28-r1 (linux kernel 18.104.22.168 )
But, with the same versions of the programs and a new kernel:
gentoo-sources-2.6.28-r2 (linux kernel 22.214.171.124)
X is starting and working correctly.
*** Bug 21265 has been marked as a duplicate of this bug. ***
FYI, I do get the same kind of problem with 126.96.36.199 on a 945G system
xorg server 1.6.0
Peng, does this still exist in the latest kernel?
