It's rather a question of what the switch on the other end of the  
cable was configured to.
Some switches don't like auto-sense. Some like it, some prefer it.  
Some only like "Auto-Sensing" to Gigabit etc.pp.
It's a funny game.
I just try to keep everything to "auto", because I feel switch and  
interface-cards should be able to do what their vendors advertise:  
autosensing.
