Sorry, OK.

Hmm... I didn't tried the official Debian lenny kernel because my box
is so geared towards grml, I don't know if any of my HW will work
without grml's auto detection mechanism. Moreover, I presumed that it
should not be any problem since Debian lenny is the *stable* release
that is used by hundreds and thousands of people. Nobody has such
issue when I was asking the question on debian user mlist.

As for testing on real hardware, I just tried again. No, alsa does not
work either. So it *is* universal. Actually, I noticed that the alsa
problem starts with linux-image-2.6.26-grml_grml.07
(linux-image-2.6.26-grml_grml.05 is fine, and I don't have
linux-image-2.6.26-grml_grml.06).

aufs-modules-2.6.28-grml is using the latest aufs while
aufs-modules-2.6.26-grml is not. aufs-modules-2.6.26-grml does not
include the previous mount.aufs file, thus:

% mount -v -t aufs -o br:/aufs/day0:/aufs/base none /aufs/u
none on /aufs/u type aufs (rw,br:/aufs/day0:/aufs/base)

% mount -v -o remount,prepend:/aufs/day1,mod:/aufs/day0=ro,del:/aufs/day0
/aufs/u
none on /aufs/u type aufs
(rw,si=f631fe5e,xino=/aufs/day0/.aufs.xino,br:/aufs/day0=rw:/aufs/base=ro,prepend:/aufs/day1,mod:/aufs/day0=ro,del:/aufs/day0)

Not as shown in man page.

thanks
