Well just for completeness I tracked it down to
724c80e1d630296d1324859e964d80d35007d83c
which git describe shows as v2.6.36-rc5-456-g724c80e, so while it is a
technical regression, it took a long time for anyone to notice.

I think we probably need a more invasive patch in any case, as there
is still a race between when the drm midlayer calls pci_set_master and
the sanity enforcement, which we should close by moving pci_set_master
into the drivers (midlayer design yet again for the win).

so I'll leave it for -next.

Dave.
