AFAIK, the specs for gigabit specify that all devices must support auto
MDI/MDIx (in otherwords, automatically detect whether crossover is
required or not). I also don't believe that gigabit uses all four pairs,
it still only uses 2 pairs, and even 10M full duplex will use all four
wires (2 pairs) simultaneously...

My suggestion would also to avoid any bonding/etc until you have things
working properly.
