I think you hit the nail on the head there.. It seems to work now with
DOS set to 7 instead of 0 as it defaults to.

Funny thing is that I know remember going through this issue some time
ago.. I have since then changed from ubuntu to debian lenny. It used to
be taken cared of by a hotkeys script in init.d and I have now installed
 the corresponding debian package for that and all is well.

Many thanks for your help, funny how fast one can forget sometimes..
Strange though that I did not have any issues with 2.6.28, 2.6.29 (not
that I can remember at least).
