Pentium-M was a single core laptop chip about 4 years ago, that predated
the Core family of CPUs... The current "Pentium" dual core chips are
low end Celeron-style chips based on Core2Duo chips with smaller caches
and disabled features..
Some potential places you get into trouble moving linux...
1) old architecture was x86_64, new CPU isn't.
2) old board and new board require different device names for the
disk systems, so /etc/fstab has to be editted
3) new board requires different IO drivers in /boot/initrd-*.img
