According to RME, this limits the number of tracks one can record/playback, but I don't know if it could affect playback quality of a single stereo track. My own laptop has identical Ricoh controllers, and after some wrestling, I got them working. For me, one of the keys was disabling ACPI's PCI assignments to get the card on the proper IRQ. But Tim already tried that [right?], and I have already sent him my kernel config, so I am a bit out of ideas....
