    Hi,

    Oh yeah I didn't really check, but I knew there was some file saying
    what version was required (changes). It's kinda tedious to check these
    things whenever you upgrade a kernel but from 2.4 to 2.6 is obviously
    a big change. I actually read about it in
    Documentation/post-halloween-2.6.txt I think.

    It does, I think the version number may simply be wrong.

    You normally don't need a modprobe.conf, everything should be in
    /etc/modprobe.d. modprobe.conf is just an empty file on my system. I'm
    not sure what happened now. It seems you used the correct name and
    such, so I'm not really sure. I take it module-init-tools was
    installed before you configured and compiled your kernel?

    There is one hint in the post-halloween doc:
    - Some (older) versions of 'mkinitrd' don't search for modules
      that end with .ko, so update your mkinitrd if this is a problem.
    Did you make an initrd image?

    Yes, pretty annoying that most guides assume that you don't have
    modules in kernel. Just configure the module in your kernel. Install
    those modules, install alsa-base and alsa-utils and then try running
    "alsaconf". With a bit of luck that should configure everything (as
    soon as you got the module problem from above sorted out, that is).

    greets,
    Wim
