That is exactly the behavior I would expect with that configuration. Any time you have one side of a link trying to negotiate when the other side is not, the negotiating side (in this case, the switch) is going to fall back to half-duplex. You have the router set to full duplex - thus, you have a duplex mismatch.
I find it hard to believe that the router card does not support auto-negotiation. However, if it doesn't then the solution to the problem is to set the switch port to 100/full.
