We do see a lot of PGTBL_ER: 0x00000049 on 845G chipsets. The intel developers are still scratching their head about this. This is what Chris Wilson writes:
We have big issues with GEM on i8xx. i845 is even more troublesome as it has
some errata that we fail to workaround that affect reprogramming the GTT.
My presumption is that this is the very same bug, and the current workaround is
to use UMS+EXA.

We have a master bug report for this issue at bug 541492. Marking as a duplicate of that.
