Comment:
Today tried a different route. Installed breezy and upgraded to dapper. No major problems. But, even the new kernel in dapper (2.6.15-19-386) does not boot. But, 2.6.12 boots.

Additional problem is I do not have a working X now. After loggin in the gdm, I get the message

   I could not start your session and so I have started the failsafe xterm session.....

There is just one gnome-terminal windows minus the window decorations. Alsa is not loaded.
