I've now confirmed that it is the latest grml 2.6.26 kernel,
linux-image-2.6.26-grml_grml.08, that breaks my alsa. Here are my test steps:

- leave linux-image-2.6.26-grml_grml.08 and go back to alsa-base_1.0.17.dfsg-2
  NOK, even after reboot

- while keeping alsa-base_1.0.17.dfsg-2, go back kernel to
linux-image-2.6.26-grml_grml.05. Yes, problem solved. 

So, mika, I'll leave the issue open, since you are still maintaining grml
kernels v2.6.23, 2.6.22, 2.6.20 etc, and let you decide what to do with
linux-image-2.6.26-grml. 

FYI, my test shows that linux-image-2.6.26-grml_grml.05 does not work with
alsa-base_1.0.17.dfsg-4.
