seg fault with cat /proc/comedi

I'm installing RTAI-Lab according to the RTAI-Lab tutorial.
My system is Ubuntu 6.10 and vanilla 2.6.17.10 kernel patched with rtai.
I'm trying to use an old ISA card, a DAS800, and trying to do
comedi_config -v /dev/comedi0 das-800 300. dmesg seems like it has
probed it as DAS-802 but pccardctl info produces nothing.
And cat /proc/comedi produces segmentation fault with dmesg claiming a bug.
Any hints of what I should try? Any hints greatly appreciated.
Thanks,
Mats

and cat /proc/comedi produces segmentation fault and another dmesg
produces this:
