Yup, works fine now (tested two laptops; one x20 and one x21)! Thanks!

Hmm, the very latest CVS-tree seems to work differently (rc1 -> rc3). Now
that post-rc3 snd-cs4281 works with my laptops, I'll try to reproduce the
problem.
BTW; The cs4281 compilation problem I reported earlier is definitely
a compiler issue. On two different laptops (x20&x21 thinkpads),
compiling with the RH72 gcc 2.96 produces a snd-cs4281.o that fails
to recognize the soundchip. By adding one "(volatile*)" (that shouldn't
have any effect), driver works on all laptops. This happens with
current CVS and all 0.9.x release candidates. So beware
of that gcc version.
