The Intel one definitely broke -- I don't know about the others. There
are some old patches at http://people.freedesktop.org/~zhen/agp-mm-*
which make it look like _all_ AGP drivers are broken.
I wouldn't bother adding the workaround -- as I said, I'm planning to
rip it out of 2.6.32 (and in linux-next as soon as it's reasonable to do
so). Let's just let them fix it.
