Axel Dörfler 0c67510ae1 Enabled SMP detection again - since it's very likely that it doesn't work on
your system, I've also added a "Disable SMP" safemode option. The NO_SMP
define is still there, and will be removed once SMP works flawlessly.
Prints out infos about the interrupt entries in the MP config.
