Finally I got a connection without 'trims' or modifications, just WAITed some minutes (3-5') till my broadband connection appeared to network manager icon.

System info:
------------
pc: asus eeepc 1000h
os: Lucid Lynx alpha1 + updates (14-Dec) kernel 2.6.32-8-generic #12
3g: ZTE MF636 19d2:2000 (when attached) 19d2:0031 (when connected)

Notes:
------
1. my system runs from installation on SDHC card (maybe slower)
2. wifi and bluetooth were enabled

Results:
--------
Although looping creation/disconnection of ttyUSB0-1-2 happens (as in previous comments) the connection made. I realized that port numbering (ttyUSBx) is stable (0-1-2) as below:

[ 193.944529] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2
[ 193.944615] option 1-3:1.0: device disconnected

[ 206.182341] usb 1-3: GSM modem (1-port) converter now attached to ttyUSB2

Extra info:
-----------
Attached is the dmesg I got doing the following actions:
0. boot without modem, wait for the system to fully load
1. sudo dmesg -c # (to clear initial lines)
2. modem attached
3. click on network manager every 20 seconds till the pre-configured mobile broadband connection appear as selection
4. dmesg > Desktop/LLa1_dmesg.txt
5. try & suceed connection via network manager
