But these drivers did work in earlier kernels, yes? 2.6.20 worked, but
we don't know about intervening kernels.
Can you tell us which version(s)?

That would be great - a git-bisect is often ideal.

Linus' tree is also broken.
I tried a Linus 2.6.24-rc4 and it acts the same way, with a very slow
transfer rate.
I also tried 2.6.24-rc4 with the older not-libata PATA drivers and it is
broken. dmesg had a line about the CF card detected as hda,
but /sys/block did not have hda and /dev/hda did not function.

Oh, OK. Hopefully the ata guys can help out with this.
I don't know if it actually strictly a regression? Did libata ever support
that device in any earlier kernels?
Alan will be non-respnosive for a few weeks.
Maybe pata_pcmcia-minor-cleanups-and-support-for-dual-channel-cards.patch?
Could you try a `patch -R' of the below?

It might be that it auto-configures for PIO-0. I have no idea why it
does that.
Another interesting thing is that doing a dd to or from the card brings
the rest of the system to a nearly complete halt. Interrupt problem?
