I also have a ricoh chipset, and I'm considering to by a FA-101 to use with Linux (I use MOTU with win). Currently I'm still using 9.10 on the audio-laptop by have 10.10 on my netbook, and I'm studying if I should move to 10.10 on the audio-laptop. Your email is a help towards that, cause 8ms is low for my standards :)
