Hello!
It looks like what they're doing is making you compile these drivers into the kernel - which is what had to be done for a LOT of peripherals in the earlier days of Linux. Apparently, from what I've read, these drivers are not yet included into the Linux kernel.
Just to be safe, I'd update kernels, make sure the updated kernel is going to work OK for you, then run this on the updated kernel, or a kernel other than the one you're using now. That way, it'll be easy to revert back to what you had if something goes wrong.
Lastly, keep in mind that every time you update the kernel in the future, you'll have to keep doing this until this driver is finally incorporated into the kernel - either by Jerry or by Ubuntu. In my somewhat-less-than-humble opinion, the folks who made this pup should've written a script to do all this for you...
