100Hz is as fast as can be conveniently arranged. I would recommend
fixing your modem configuration instead. If you post the output of
'pccard dumpcis' and the /etc/pccard.conf entry you're using, along
with the resource allocation details from the top of /etc/pccard.conf
and the IRQ usage for your system to mobile@freebsd.org , we can
probably sort it out.
