Hi,

I'm actually using a similar combination on my gentoo without problem
(PCI card).

AFAIK the only difference between 2.6.30 and 2.6.31 for the hdsp is a
patch I made allowing the firmware to be built inside the kernel. It
should not have this kind of side-effect.

I'll check on my notebook with the PCMCIA card as soon as I can.

If you're using a custom built kernel you might want to try with the
firmware built-in.
