Ok, if you think that would be possible. I assumed that it was broken

alsa-driver-snapshot.tar.gz README says "integrated to 2.6+ kernels", so
I assumed that this somehow only applied to 2.4 - which obviously would
be very strange.
I missed the big overview. It seems like it would have been helpful to
me (and the next guy) if something like the following blurb could be
found somewhere - in README or INSTALL or from the "How do I install the
ALSA driver from source" link or on
"ALSA project develops both Linux kernel drivers as well as support
libraries and tools for user-space. The kernel drivers are also included
in vanilla Linux kernels, and usually the stock drivers are fine and
should be used. It is however also possible to build the alsa-driver
kernel modules for an existing compiled kernel and replace its drivers,
for example from alsa-driver-snapshot.tar.gz to get the latest ALSA
development and fixes. Note that the modules will have to be rebuild
when a new kernel is installed."
INSTALL is very demotivating for use with distribution kernels. It would
be helpful if you could add something like:
"On Fedora 11 (with PAE kernels) it works fine, but you need the package
kernel-PAE-devel of the same version as the running kernel-PAE."
might also be helpful.
I assume something similar applies to Suse.

Ok, thanks for the hints to help me understand.
I will try alsa-drivers-snapshot and alsa-info.sh next time I get access
to that computer - that will probably take more than a month.
