I don't really recommend that folks install the driver this way as a
permanent solution, as it will replace files supplied by the packaging
system (which will then be overwritten on upgrades), though it would be
useful to know if the new version does in fact fix the issues.

The correct way to do this is to run:

sudo apt-get install linux-headers-`uname -r`

which gets only what you need (the kernel headers), in a single step, and
works properly across upgrades.
