BTW the V.35/V.24/X.21 version (i.e. non-T1/E1) are supported by the
pc300too.c driver. Or at least they're supposed to, I admit I haven't
used this kind of hw for several years (but can still test and fix, when
time permits).

Perhaps, just perhaps, merging T1/E1 support into pc300too.c would be
a better idea than dealing with Cyclades' old code.

The pc300too shares common SCA-II code with a driver for another hw,
pci200syn. I think it's been verified to work on non-x86-32 systems.

Esp. given this:
