This sounds like a bug recently reported by Uli Weigand. BenH
said he'd take a look, but it probably fell under the table.
The problem found by Uli is that on certain processors (Cell/B.E.
in his case), the DABRX register needs to be set in order for
the DABR to take effect.

Just as a note, the PS3's lv1_set_dabr(), which we used for
ppc_md.set_dabr sets up both the DABRX and DABR registers.

Yes, I know. I tried it on the PS3 first and couldn't reproduce
the bug he saw on the blade.
