it would be cleaner to make this dependent on your chipset/vendor-id -
look how OHCI_QUIRK_INITRESET gets activated for e.g. SiS
(PCI_VENDOR_ID_SI) and OPTi (PCI_VENDOR_ID_OPTI). What is your box's
pdev->vendor and pdev->device? (lspci -v) (If it's indeed a quirk that
is needed, not some other fix.)
