OK, the problem is that the ricoh-mmc driver in hardy only works for R5C832 chips. In the latest git it also works for RL5C476 chips (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=882c49164d72c45f37d7fa1bb3de7c31cf1a5fab)

Unfortunately I have a R5C552:
04:09.1 FireWire (IEEE 1394): Ricoh Co Ltd R5C552 IEEE 1394 Controller (rev 09)

I'll contact the author of the patch, how he got the info about the RL5C476 chip (there you need to poke different registers!) and whether R5C552 could also be supported.
