Kernel bump & VirtualBox

Last Wednesday updated the kernel from the 3.2 branch all the way to 3.9.

I was fed up with the occasional hangs and the problems shutting down my T430 lappie.

So far things are really good... Did a 3 day up test, with many, many Suspends, and had no problem at all.
The only thing -and it was actually something to be expected- that did not work after the kernel upgrade was VirtualBox, it even belched an error message while the actual kernel was being installed.
So, after dabbling a bit with some Google & different tips, in the end decided to simply uninstall Precise Pangolin's stock VirtualBox and then install the Raring one form the VirtualBox website.
It works flawlessly.
