iwconfig never displays the local MAC address under "Cell:".
It shows either the IBSS id choosen if it has started its own IBSS in
ad-hoc mode or the (I)BSS id joined if (a) in managed mode or (b) if it
had joined an already existing IBSS (i.e. if it was not the first STA
started for a given SSID in mode ad-hoc).

Not necessarily. Old Prism2 firmware (you didn't post which one you use)
seems to have problems in ad-hoc mode - grep the lwlan-ng mailing lists.
I had a Prism2 PCMCIA card with 0.8.3 inside which (if it started the IBSS
first) sometimes decided to leave the IBSS by itself.
Windows driver might load newer fw versions into RAM on startup.

Try starting both devices in a different order (AFAIR starting the
Atmel-USB first fixed my problem with the 0.8.3 Prism firmware - but I
used the Berlios driver).

I'm of little help with the Sourceforge USB driver.
If you could get another Prism2/2.5/3 device you may use it in monitor
mode to trace the air traffic.
