Patch from "Andreas Leuner" <al14@inf.tu-dresden.de>:

I have modified the rtai.m4 script locally to recognize a kernel with
ipipe support. With this the generated configure script detects ipipe
support and activates RTAI support. The so modified comedi compiles fine
and modules load without any crashes. However I haven't tested the result
with real daq hardware yet.
