The 2.0 series do not support 2048 byte blocksizes, but newer kernels do.
2.2.0-pre7 should work.

I didn't try that yet. Maybe autofs explictly requests the wrong
blksize. You should try to mount it by 'hand'.

Last time I had these (almost exact) messages, the drive was _very_
dirty. You could see the dust on the medium's surface. After cleaning
the medium with a cloth (like you do with a CD) and the drive's lens
with Fujitsu head cleaner it resumed normal operation.
This expensive 'head cleaner' is just a small dry brush sitting inside
a disk case. So if you want to save some money you could try cleaning
your lens manually.
But it's not my fault if anything goes wrong there...
