Yeah - I hate it when manufacturers do that too.

Surely they printed the MAC address on a sticky label on one or more of:
a) the motherboard
b) the ethernet controller / socket
c) the manual
d) the box the motherboard came in
e) a little piece of paper included in the packaging ?

I'm generally used to seeing two labels - one on the motherboard itself, and 
one on a separate piece of paper that a system assembler can stick on the 
outside of the final assembled case, in case the end-user ever needs to know 
the MAC address without booting the machine.
