I have closed #258500. For reference, this can be done by
sending a message to 258500-done@bugs.debian.org. Where 258500
is whatever bug you want to close. The contents of the mail will

Is this the same problem as 286939, just with a slightly different
version of the kernel. If so it probably would be better to just add to
that bug. I have reassigned them both to kernel-source-2.4.27 and
merged them for now.
Not a big deal in any case.

This is quite curious indeed.
What I am a little curious about is, does the medley driver rely on
accessing the discs through the siimage (or sata_sil)? If so, do
you have one of those loaded in your debian install before trying
to load the medley driver? If not, can the drivers co-exist, it
sounds like they can from your Knoppix experience, but perhaps
trying debian without siimage or sata_sil loaded might help.
I had a look at the source for the medley driver, and it doesn't seem
to have been updated for quite some time, and the latest version seems
to be both in the kernel.org and debian kernels. So it is likely that
knoppix has the same driver. I confirmed that medly.c was the same for
all of these kernels.
For reference, here is the home of the driver
