Hmmm, could you be more specific? This does not tell me anything...

You have two options. Either disable atrpms or install the kernel
manually. The "planetccrma-core-*" has very specific requirements and
those match specific versions of alsa. At this point in time atrpms has
newer versions than the ones available at Planet CCRMA, so those get
selected and "conflict" with the requirements of planetccrma-core-*.

So, you can disable atrpms (comment out the urls from sources.list and
do an "apt-get update") and then install the kernel "manually" by doing
first:
  apt-get install kernel-smp
that will list all the available kernels, then select the one you want,
probably this is what you want:
  apt-get install kernel-smp#2.4.26-1.ll.rh90.ccrma

After that you should be able to do an "apt-get dist-upgrade" to update
everything. Be aware that on another thread someone has been having
problems with atrpms because of different naming scheme of some
packages. 

I don't remember if the dependencies will cause the alsa-kernel package
to be pulled in, you may have to install that manually.

Strange, that should have helped (unless you already have newer versions
of alsa-* installed that the ones available at Planet CCRMA, I guess).

In some cases the atrpms repository seems to be choosing different
naming schemes than the rest of the repositories (see the fftw* thread,
for example). While they may be more "rational" they produce conflicts,
so at this point it looks to me that trying to mix Planet CCRMA and
atrpms is not good. Most probably dag and freshrpms do not have those
problems.

That is called "pinning" but I'm not an expert. Supposedly the atrpms
configuration has that enabled with different priorities for each
repository, maybe something has changed and broken that. 

Check what you have in /etc/apt/preferences...
