So the driver works with the pre-installed version?

Are the sources for this pre-installed Ubuntu publically available
somewhere or is it just a stock Ubuntu release? Being able to see kernel
sources from that release would help.

I didn't quite get this 2) part. How do you know that all drivers and
firmware are available? Earlier you mentioned about some special driver.

Have you tried to manually bind the device to those drivers? With very
good luck it might work (but I doubt it).

Also did you file a bug to Ubuntu? If the driver works in 11.10 but not
in 12.04 that's a regression.
