Looks like the driver is in the kernel. uname -r will give the kernel
version on whichever distro / version you're running. The specific
series of your card had issues over the summer in kernel 3.15 (and
possibly before as well), that were fixed in later revisions of 3.15.x
and for sure 3.16. Not sure on lts kernel though.

So, that said, you should have seen a variance in kernel versions
between the two Precise partitions either with the kernel and/or
firmware of the wifi card, this is my best assumption. Although you
said that didn't matter when you checked package sets?

This should also help, Broadcom plays an active role in their Linux
drivers and the kernel (site also has instructions for installing
firmware in Ubuntu):

Good luck,
