Just a follow-up on that one, i haven't been able yet to thoroughly test this patch on AGP system, so i am mostly sending so other people can test. I think i corrected few bugs that were in previous iteration of that patch. Beside that i think i have addressed all comment previously raisen, but don't hesitate to pin point any things i have miss.
