I think that is because the other controller has a PCI-X interface,
which is much faster than regular PCI. The extra bandwidth between CPU
and card is very helpful when doing software-based raid-5.

Hmm. You'd think. There is a setting for mdadm to auto-start or not.
This can be adjusted by running 'dpkg-reconfigure mdadm'.
