The driver should be entirely generic, it should depend on the PCI class
rather than the PCI id. The Linux driver (not just RH or Fedora---it's
the same for all distros) is that way, but on Windows it's possible that
manufacturers customize the driver to only match a particular vendor or
device id.
A quick Googling suggests that you want the "SDA Standard Compliant SD
Host Controller" Windows driver.
