[gentoo-user] [PATCH] Using ati-drivers with kernel 3.5

[walt]

Like the last time, this patch is an ugly hack and it needs
a professional touch before any sane dev would take it seriously.
But here it is anyway :)

BTW, I replaced for_each_cpu_mask because I still haven't learned
the correct syntax for it.  The number "4" is the number of cpus in
this particular machine.  You should use the correct number for your
machine, obviously.
