Well, the patch does have effect only when you enable MSI.  And, MSI
is disabled on many ATI chipsets as default unless you patch the
kernel.  I suggest it just to check whether any unknown IRQs are
issued or the hardware is just screwed up.

It looks like this is a generic problem of ATI SB chipset.  Which
model is it?  SB450, SB460 or SB600?
