Greetings.
Since my last post on the topic, I've been able to get ALSA working on
my system. To start with, I got the cvs drivers working with
2.6.15-nitro3, and then I got the in-kernel drivers working with
2.6.16-nitro_git3. Actual use of the soundcard is fine in most cases -
some formats 'lock' the media play, but this is another issue :)
However, when I rmmod the drivers, which happens when I reboot / halt, I
get a kernel oops:
