Are you sure you picked up the new kernel? Try "objdump -d" on vmlinux and verify that itlb_fault ends with "b0" being restored.

Yup; a kernel with Asit's patch fails if CONFIG_DISABLE_VHPT is on, succeeds if it's off. Oddly enough, I got an 'illegal instruction', IIRC; the oops address was inside page_fault.
