seems to be a kernel bug in 2.6.12-rc2, where REAPURB[NDELAY] can return
NULL pointers.  Greg KH's kurrent patchest on top of -rc2 fixes the
problem.  I've now been able to run the wfm_rcv_gui.py and listen to FM
radio :)

I'm now trying to get the same setup running on my notebook (Apple
TiBook IV, 1GHz G4, PC-Card USB2 Adapter).  For some reason debian
unstable doesn't provide the same version of wxPython on ppc than on
i386/x86_64.  Need to investigate why...

btw: My first project for the USRP will be passive sniffing of
ISO14443 A/B (the on-the-air protocol used between rfid readers and tags
or contactless smartcards).  I'll keep you posted on my proceedings.
