Just to give an update, I did a little more work on it and found that
the call to lv1_insert_htab_entry() inside ps3_hpte_insert() is
failing.

   http://git.kernel.org/?p=linux/kernel/git/geoff/ps3-linux.git;a=blob;f=arch/powerpc/platforms/ps3/htab.c;hb=HEAD#l70

The values of the variables printed all look strange compared with
commit 048ee0993 reverted.  I'll try do some more work on it this
week.
