Sigh, I had no chance to test the driver on this chip myself... And I also
haven't tried the driver on SATA drives at all... :-/

Some patch was recast, maybe this was the reason...

I'm surprised that this has even compiled! It has check_in_drive_lists()
defined twice...

You may find the summary patch in the -mm tree I guess if you hit the V
link against the -mm patch at the top of www.kernel.org page, like this one:

http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fpeople%2Fakpm%2Fpatches%2F2.6%2F2.6.18-rc1%2F2.6.18-rc1-mm2%2F2.6.18-rc1-mm2.bz2;z=647

Hm, looks like the drive is wrongly reported as blacklisted or the cable
being somehow misdetected... Ah, this was SATA drive, you say?

I also would, at least UDMA(100)... :-)

Output of hdparm -iI /dev/hde would also be helpful.

Well, this looks sane...
