I am on a Geode LX system with CS5536 audio chipset. Using 2.6.32 in Lucid, OSS4 worked great. With 2.6.35 in Maverick, the modules load, no errors are produced besides a warning that my feeble hardware is incapable of mixing multiple audio streams, but no OSS4 audio. I had the same error/warning in 2.6.32, but had working audio.
As per the forums, other people on other architectures are merrily using OSS4 on Maverick. I have thus deduced the issue to be CS5536 specific, in the 2.6.36 kernel. I don't know if it is Ubuntu-patch related or 2.6.35 mainline related.
