I used to think that I wanted to use that driver too, but it's not
going to work.  It's because I've got the version 1 of the chip, not
the newer version 2 or higher version.  

It looks like you really mean for me to use the hpt3x2.c driver
instead, since that's the only other one which mentions the
PCI_DEVICE_ID_TTI_HPT302 device id in it's init method.

I don't think it will work here, it won't even touch the card since
the pci_device_id won't match at all.  The htp366.c only looks at
HPT366 ids, while mine is an HPT302 id.  

As a quick note, 2.6.21-rc7 is working just fine here.

Ok, so do I need to do anything special with the next -mm release and
the next version?

Thanks,
