The problem appears to be that auto-negotiation is not working at
1000mbit.  Either this is a bug in how etherboot drives the card, (I
haven't tested that combination) or it is a bug in the switch?

Does it that card and switch combination work in Linux?  (If you boot
from disk?)  If so there is a way to get it working.

I don't have the context to interpet the above. phas2/phase3?
