Stac/LZ compression with ISDN - anyone know how?

[Phillip Deackes <gsmh@gmx.co.uk>]

Does anyone know how I can get to enable Stac/LZ compression with ISDN?
I have a BT Speedway (=Fritz AVM PCI card). I have beenreading the
isdnutils HOWTO but although it mentions Stac compression it does say
how it can be enabled. I gather it is a kernel option but it appears not
to be available when I go to recompile. I am using kernel 2.2.15 and
Debian Woody.

Cheers.
