NIC device names changed

[stan]

I had a hardware failure, and as a result the motherboard (which hs built
in NIC's) was changed on one of my 10.04 machines. Now the devices whic
were eth0, and eth1 are showing up as sth2 and eth3. 

How can I fix this, short of reconfiguring all my networking? And is there
a way to prevent this (truly ugly) behavior in the future?

Thanks.
