what X and Y are you talking about? I have 2.6.20-15.27 running here and
so far no kernel update has so far caused any problems.

How did you recompile your alsa installation?

make clean && make will not make you happy, you should do it like this
% cd $WHERE_ALSA_1.0.14rc3_IS_UNPACKED
% make clean
% ./configure --with-kernel=/usr/src/linux-headers-2.6.20-16-generic
--with-cards=hda-intel
% make 

If you don't (re)configure, your old kernel sources will be used as
headers resulting in possibly misbehaving modules.

BTW, dear ubuntu audio team, is there the chance that we ever see an
updated alsa package for this bug? using rc3 or even better rc4 and
applying the patch will make life easier for _many_ users out there and
it doesn't sound too difficult or dangerous after all ...
