About bisect:
None of the kernels work from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D, that is v2.6.24 and above
(With "2.6.24-020624-generic (root@zinc) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Wed Feb 25 23:56:54 UTC 2009" no sound devices were found and v2.6.15 could not be installed).

Hardy Heron installation media has kernel
2.6.24-26-generic #1 SMP Tue Dec 1 18:37:31 UTC 2009 i686 GNU/Linux
Ubuntu 2.6.24-26.64-generic.

Regression in kernels from 2.6.25-020625-generic onwards., at least.
