I'm guessing nobody is using this anymore. I would be really surprised
if anyone is. Let's test my idea. Hands up anyone that has:
- a PCBIT ISDN-card ("manufactured in Portugal by Octal", according to
  its Kconfig entry);
- a working X86 machine with ISA;
- a working ISDN line;
- and, say, an ISP picking up the stuff you send down that ISDN line
  at the other end;
- and cares how 2.6.32 (and higher) runs that setup.

[Crickets.]

Besides, it is, apparently, an I4L driver. (Though there's a CAPI part
too. I need to check how that fits into the picture.) I4L is deprecated
for ten years now (or is it even longer?).

Perhaps pcbit, and the other I4L drivers, should be (finally) tossed
out? That was discussed last year too, but nothing really was decided.
