Title: no longer removes running kernel

doing a regex match instead of string compare fixes a bug where the currently running kernel (and modules etc) were purged if there were more than three newer kernels available.

you can reinstall the running kernel with 'sudo apt-get install linux-image-$(uname -r)' if you feel the sudden need to modprobe, or reboot into the newer available kernel for great justice.
