I have looked at the list archive on gossamer-threads.com for solutions. With Fedora Core 6 unsupported (the last kernel for which my zip drive worked), it is time for my last attempt at a solution. Please CC: any response as I have not joined the list. I have compiled a kernel-debug RPM and can run this if its output would help.

I assume AHCI is correct?
AHCI is better, yes. It shouldn't be relevant this this problem though.

That is rather curious. There's no sign of any libata error handling going on.. Maybe the drive is actually returning that error code in the ATAPI CDB, or at least we think it is?
You are sure that this drive still works with older kernels using drivers/ide, and that the hardware didn't break at some point, I assume?
