Yes, that was my suspect too (see the later mail I sent).
I'll give your partial revert a try.

Well, that's not yet available in current Debian kernels. I did test 
pata_cmd64x once (way back in July 2007, when Alan Cox requested it), but 
have not used it since as I normally run distro kernels on the box.
When I build the custom kernel with your patch I'll activate it and give 
it a try again.

Thanks,
