It sure would be nice to know why the card reader has problems with the commands sent by 2.6 but not 2.4...
I finally got Fedora's 2.4 kernel rebuilt with debugging.. Here's what it looks like in 2.4 which never fails:

And a sucessful insertion on 2.6 looks like:

The only immediate thing that stands out to me is that in 2.4 the INQUIRY is '12 00 00 00 FF 00' (Allocation length 255), while in 2.6 it is '12 00 00 00 24 00' (Allocation length 36 (makes sense)).
