I am trying to reproduce the problem, but i cant invoke the reenumeration even 
with not-patched kernel. I was before playing with the modem and disabled the 
GPS with:

	AT_OIFACE="GPS",0

could this also affect somehow the reenumeration? I also wonder if we could 
save some power by disabling gps - and maybe something else from this:

AT_OIFACE?
DIAG: 1
GPS: 0
APP1: 1
APP2: 0
PCSC: 0
IP: 1
MODEM: 1
VOICE: 0
SD: 0
CD: 0

I wonder what "IP", "APP1" and others mean. I couldnt find any documentation 
on this...

Anyways i have cherry-picked your commit for next qtmoko version and i will 
now comment out AT_OPSYS=0,2 to enable 3g and we will see if the reenumeration 
will be gone. And i could finally get rid of the ugly patch that deals with 
reenumeration.

Thanks a lot for the work!
