Oh, that's good to know, I guess that's the best option, since after
the system is up and running I can do whatever optimizations it needs,
as long as I'm able to boot and work with it in the new hardware.

Tonight I'll start the (long and boring) process of recompiling the
whole stuff with "-mtune" instead of "-march".

Thanks to all that replied so far... Maybe more suggestions comming?!
