The 3w-9xxx driver in 2.6.25 already calls 'pci_try_set_mwi(pdev)'.

Agreed. But RHEL/Centos doesn't update "their" kernel as much as the main tree.
And, I'm not really willing to have a much different and less tested
kernel (in RHEL/CetnOS context, that is) as the one provided by
default.
Anyway, I was just willing to let you know that the fix works fine
with others than 9550 controllers ;)
Regards,
Laurent.
