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
