More news, not all good. After trying out all combinations and doing it
again to be sure it seems that:

* kernel26-2.6.39.1.3-1.1-i686.pkg.tar.xz and its hdspm driver work well
on the five machines that have cards with firmware revision CC.

* With newer cards (they arrived just two weeks ago) with revision CF
things seem to work but there are crackles in the sound - not loud but
clear enough. Sounds like single samples being modified every now and
then.

    - Older cards on the same machine with the same kernel work fine.
    - Kernel 2.6.37 on the same machine with the new cards works fine
      as well.

So there must have been some regression.

For now I have to revert two machines (those using the new cards) to
2.6.37. 

Ciao,
