Asus eeePC 1201T

model=eeepc-p901

No or all other models, I tried (which does not include: "basic", "quanta", "lifebook" of the alsa list shipped with 10.04), lead to high CPU usage (pulseaudio, xorg), buggy behaviour, freezes (see here)

This model manages to supress internal speakers, when something is plugged in on "line-out" but does not manage to make the internal microphone work.
