Thanks, that's working, verbatim:

usb_modeswitch -v 12d1 -p 1f01 -V 012d1 -P 014db -M "55534243123456780000000000000a11062000000000000100000000000000" -W

After that, if_cdce and uether kernel modules are automatically loaded
and dhclient ue0 successfully acquires IP address.

And it is working in 9.2-STABLE, 10.0-STABLE systems I tested with no
modification to sources, so this is a good solution for me.
