Still cannot get this to play. Kernel boots up fine loading of any alsa fails with a bunch of undefined symbols. I am using neither udev nor devfs (no longer in kernel)--based on an old knoppix hdinstall, upgraded to Debian Sid. Kernels through 2.6.11 worked fine. 2.6.12 --mpu401 fails, 2.6.14 alsa audio fails. Fun.
