Yes, I got many useful tricks, a big thanks to all.

Okay, let's get the numbers.

I followed Sven and Stephen's advice so I:

- Used "make localmodconfig" to generate the ".config" file
- Appended "CONCURRENCY_LEVEL=2" to "make-kpkg"
- Added CONFIG_MATOM=y (just in case...)
- Removed the aforementioned "CONFIG_LGUEST_GUEST", "CONFIG_LGUEST" and 
"CONFIG_PARAVIRT_SPINLOCKS" options from the ".config" file

This compilation round started at 18:56 and when I came back (at 21:05) 
the process was already finished...

Wow, I didn't expect that. 

So what time it took? I should have used "time" to monitor the proccess 
(my bad) but the generated ".deb" file says it was last changed and 
modified at 20:07.

If that's true (which results in ~1 hour of compilation time) I can 
consider myself very much fortunate :-)
