Applied.

However, the patch itself didn't apply cleanly, because in my souce tree,
these two lines are in a different order:

but I actually think your order is the *correct* one (because I'm not at
all sure that config space writes are even guaranteed to make a difference
when in D3cold).

So I wonder, did you have some other fix applied to your "original" tree
(it sure isn't original 2.6.23, since that whole suspend/resume code was
added later.

Maxim? Mauro? Pretty much all other drivers do

pci_set_power_state(pdev, PCI_D0);
pci_restore_state(pdev);

in that order, and I really do think that D3cold is allowed to not
actually react fully to all config space accesses (ie we have to re-write
them after bringing it out of D3)
