Well, the kernel module crashes, so no go on sound. I mailed the alsa-dev mailing list with details. I guess I could try ALSA for 2.4, but I'm kinda bored of it all now. I don't really want to learn ALSA, either.
In good news, though, 2.6 is fast. Much better X performance... better DRI? I dunno. Don't really care... it's just a lot nicer. I look forward to trying this on servers one day.
