If the module doesn't even get installed, or the kernel does not report
any card as recognized, you could tweak the initialization routines to
add PCI IDs for your own cards, and hope they work correctly.  If the
cards are recognized, there should be nothing to worry about: either
they work with zaphfc or they don't, modulo interrupt troubles.

Yes.  But not an Ethernet cross-cable, an ISDN cross-cable; there's a
pointer on the wiki to a page on isdn.jolly.de explaning how the cable
should be made, and suggestions about how to take advantage of a disused
NT.  I reckon that telephony folks call it an "ISDN TX/RX" cable.

Yes, the bus should be terminated (so the resistors don't have to be on
the cable itself).  A full description of the bus is in the ETSI
standard for ISDN layer 1 (www.etsi.org).
