Back in 2002 I took the HDD from one PC, put it in a different PC, worked just fine. The worst thing that could happen is that the other one already had another disk so I had to change /etc/fstab to say "hdb" instead of "hda" and vice versa. Didn't take long for that to get fixed by specifying UUIDs and having initramfs sort it out.

IDK why it's not working for you but this should all just work without bothering with any configuration, drivers, or whatever.
