I've compiled the firmware and tested it.
It works perfectly. Here is some dmesg of OpenWrt boot. The 3g dongle is
detected in 15 seconds.

It seems the option driver is actually working with this device. It's able to
distinguish between modem serial interface and storage interface. FYI, no
storage driver is compiled due to limited size of flash memory - only 4MB of
flash.
Finally, here is ip address obtained via ppp, with the modem device on ttyUSB1
root@OpenWrt:/# ip addr ls 3g-wan
9: 3g-wan: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc
fq_codel state UNKNOWN group default qlen 3
link/ppp
inet 10.215.213.41 peer 10.64.64.64/32 scope global 3g-wan
valid_lft forever preferred_lft forever
Looks good, isn't?
Thanks.
