Yeah, that's the right one.  But if you are technically apt,
then perhaps you could try a brief experiment for us:

Use drivers/ide instead, and see what it reports in the boot log.

One simple way to do this, is to boot a Knoppix CD, say v5.01 or so
(but not the newest version, which probably uses libata instead).

Then just grab the boot log with dmesg, and post it here.

Ok, recompiled the kernel with the old driver, here the relevant dmesg output.

Mmm.. no phantom device showing up there,
so I suppose what's left of my ancient device probing
is still mostly working (does any of it remain now?).

Tejun?
