By definition if one side is auto and the other is fixed, you'll
go end up with half.... however one side will probably believe
it is full and the other half... and many switches will dumb
it all the way down to 10baseT half because of all of the errors.

Speak up network guys!

My understanding from my own experience:

Auto+Auto=works
Auto+Hard coded=no workie (theplanet.com)
Hard coded+Hard coded=works if both set the same
   (this is what ntlug.org is doing now that
    I know they hard code their ports)
