[CentOS] loading modules across reboots

I have a CentOS 5.2 install on a machine with the Marvell nic issue outlined in
http://bugs.centos.org/view.php?id=2612. I have a few questions regarding this, what
does the # echo "11ab 4364" > /sys/bus/pci/drivers/sky2/new_id line do? Obviously it
starts right after but what specifically is the "11ab 4364" part? Also, how do I get this
to load across reboots? I have the alias and module in my modprobe.conf but that is not enough.

Thanks,
