I tried some of these options but none of them seem to help.
I also tried some older Debian kernels and 2.6.34-1~experimental.2 is
working fine, while 2.6.35-1~experimental.3 (and later kernels I tried)
is broken, so I guess the problem started between 2.6.34 and 2.6.35.
Maybe I'll try to bisect now...
