Remove compiled kernel modules during uninstallation

[kip@…]

Whenever a Linux kernel is uninstalled, the Virtualbox modules that were installed for it remain behind. e.g.

$ find /lib/modules/3.2.0-27-generic/
/lib/modules/3.2.0-27-generic/
/lib/modules/3.2.0-27-generic/misc
/lib/modules/3.2.0-27-generic/misc/vboxnetflt.ko
/lib/modules/3.2.0-27-generic/misc/vboxdrv.ko
/lib/modules/3.2.0-27-generic/misc/vboxnetadp.ko
/lib/modules/3.2.0-27-generic/misc/vboxpci.ko

This should be simple to rectify with some kind of hook for the right event with the system's package manager.
