NetworkManager and my Palm Centro don't work

[Scott Chapman <scott_list mischko com>]

I've got Ubuntu 8.1.0 and NM 0.7.0
I have and older installation (Ubuntu 7.10) which uses the the cdc_acm 
driver with my Centro and it does ppp connectivity.  I was hoping to get 
the NetworkManager to do the job with it's Mobile Broadband.  I've done 
the following:

When the Centro is USB connexted and the USBModem program run on it, 
Ubuntu loads the cdc_acm driver which creates a /dev/ttyACM0 device. I 
made a symlink from /dev/modem to it and added  myself to the dialout 
group in /etc/group.

I added a new Mobile Broadband connection but it doesn't show up in the 
NetworkManager.

Obviously, I'm missing some pieces.  How do I make it work?

TIA,
Scott
