Ubuntu releases every April and October. So we've got a couple months 
yet. I found links where somebody has packaged up a firmware loader for 
the Qualcomm modem, but it requires a package called qcserial to do it's 
job, and that apparently requires 9.10 (10th month, October). You could 
do it now if you installed the latest beta kernel, apparently, but I'm 
not in that big of a hurry, since I've got it working well enough, as 
witnessed by this message.

 > sudo modprobe usbserial vendor=0x05c6 product=0x9212
This command is run at the terminal command prompt (terminal in the 
accessories group in Ubuntu Netbook Remix).  Just past it in and run it. 
This needs done only once after/when you boot, so that modemmanager can 
find the device. The vendor and product values come right out of the 
lsusb command, ie, Bus 001 Device 004: ID 05c6:9212 Qualcomm, Inc. I 
believe it returns some sort of an error message, which you can just ignore.

After you make the tty device with the usbserial command, you can 
double-check the results with the "ls -lha /dev/ttyU*" command in 
terminal. You should see:
rw-rw---- 1 root dialout 188, 0 2009-07-23 11:29 /dev/ttyUSB0
The ttyUSB0 is what modemmanager is looking for. Displaying this is not 
required for it to work, just to double-check that it did work. And, of 
course, if the modem is not 9212, the usbserial command won't work.
