You've probably checked this, but make sure the cable is good.  I've had 
a bunch of problems with crossover cables in particular.  For example, I 
worked on one board that had no problems with the crossover cable under 
Linux, but under U-Boot, TFTP just wouldn't work.  Using an Ethernet hub 
alleviated this.

I also have a Sony notebook computer that connects fine over a crossover 
cable to a 10Base-T card, but not to a 100Base-T card.

Consequently, I've pretty much given up using crossover cables, for the 
time being.
