thanks! I only had time to try out blanking a cdrw-disk after a boot,
and it worked right away! The kernel didn't cry about anything. This
is clearly a good sign, because previously I couldn't blank a cdrw no
matter what I tried.

I'm pretty sure I did (if it was the default). But I'm not 100% sure.
Next I'll have to try burning a 1:1 cd-audio with cdrdao. If that works,
then I'm convinced everything works. :) If not, I'll post the new errors
here as well.
