Well, I have commit rights on X git :-) But the current X code is too
hopeless to warrant anything but a quick hack which I don't want to do.

Well... if the real fix means suddenly nobody can use X ...  I'm sorry
but I won't inflict that one the remaining lots of 32 bits PowerMac (and
Pegasos) users. Not until there is a fixed X available. Once Ian's work
on pci-rework X.org branch is finally merged with the trunk then life
will be better for everybody.

X guys would probably expect me to fix it yeah :-)

Ugh ... I don't think so.

Cheers,
