You have to manually set the speed for these ports in the 40 port line cards. I might suggest just using a layer-2 switch and a 10 gig trunk instead to have usable auto-neg. Finance math may win if you are doing mostly 10 gig as it drops the cost per port/slot.
I certainly have been frustrated at the lack of tri-rate auto-neg SFP cards from Cisco across many product lines.
