Can you reproduce this on the latest 2.6.31-stable kernel (2.6.31.6 as of right now)?
I can confirm the same issue on 2.6.31.6 simone@simone-desktop:~$ uname -r 2.6.31-02063106-generic
I seems to be fixed. I'm succesfully running network-manager 0.8~rc2~git.20100114t223002.d20c61a-0ubuntu1~nmt1~karmic modemmanager 0.2.git.20100112t172936.a4fee86-0ubuntu1~nmt1~karmic linux-image 2.6.31.18.31 ubuntu karmic
