Whatever you do don't set one side auto and force the other side, or 
vice-versa.  Since the 802.3 spec doesn't define if a NIC has to still support 
autonegotiation features if it is in a forced state some vendors implement it 
and some don't (e.g. Cisco's devices randomly support it and then don't between 
IOS revs).

I would say, if you have control over both ends, force both - especially with 
gigabit speeds, although autoneg with the chipsets today are much better than 
stuff just a short while ago.
