Need one more modification:

It is the libata policy to prefer use of numeric hexidecimal constants
for the PCI device id, rather than always defining a symbol in
include/linux/pci_ids.h.  The PCI device ID is a single-use "magic
number" that is only used in the PCI ID table.

Therefore, when your patch changes the hex numbers to constants, it is
reversing that policy.

Instead, please submit a patch that simply adds more hexidecimal PCI
device ids.

	Jeff
