With a nanoBTS, you don't need a real ISDN card. You can use mISDN modules which are typically compiled in as modules in Linux. My lab has a few 900 and 1800 nanoBTS units, all running over Ethernet/IP, with openBSC, Asterisk, and LCR running on VMs with no ISDN cards, no special hardware.
There is a tutorial on how to set this up here, http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR . I also found a mailing list post that fills in some blanks, http://www.mail-archive.com/openbsc@lists.gnumonks.org/msg00352.html . I would suggest trying to follow the mailing list post to the letter to set this up, and once it is working make a snapshot then try to update the source of the packages installed.
I know the tutorial. I made some corrections, too... :D Unfortunately, I couldn't get my Ubuntu Hardy working with mISDN loop without any ISDN card...
Thanks Luca
