I think it was a design problem, because the used system call only
shows those interfaces which are up. 
My approach is, to use /proc to find them, inspired by the "ifconfig" tool
(if i remember correctly).
This simply enhances get_ax25_ifaces() by this method. The code is in
the CVS version, but not enabled by default (-DFIND_ALL_INTERFACES).

I hat no problems with it on kernel 2.6. But on kernel 2.4., i observed
that when an incoming SABM occurs, the kernel did panic.
