Update: WWAN works in ubuntu lucid with a few tweaks. It needs the
binary firmware available in the default windows installation, loaded
using a specific tools gobi_loader. I found a basic how to here:
http://westhoffswelt.de/blog/0045_howto_setup_sony_vaio_x_wwan_gobi_2000_under_ubuntu_linux.html

Note that however this doesn't fully worked for me, since initially
gobi_loader seemed to hang while uploading the firmware files.
This looked to be an already fixed bug, but for some reason it didn't
worked on my system. A few more sleep(1) added to the gobi loader code
were enough to fix it.
You can check the status of the modem running lsusb, if you see a
device with 05c6:9224 it means the modem has not be initialized, if it
changes to 05c6:9225 it should be ok.

After being able to switch the device in the proper mode I also add to
create a /etc/modprobe.d/usbserial.conf with the following line in
order to make network-manager see the modem:
options usbserial vendor=0x05c6 product=0x9225

After a restart it now works like a charm, 3G connection is available
in network manager and I can connect without any problem
