Are you aware of the PlanetCCRMA project (Cced)? Activated when using
the medley-package-config. This project is dedicated to professional
audio/sound tuning kernels for low latency and providing audio
software as well as good documentation:


I don't know whether your issues can be solved (I thought for nforce2
there were OSS drivers), but if they can be solved PlanetCCRMA will
know how :)

(currently PlanetCCRMA still recommends FC1 for high quality audio, so
going back to FC1 was not too wrong, but there are also 2.6 kernels
for FC2 available for testing. Just give them a try)
