it should be possible. i've heard of some IOS versions (on the router side) not supporting interface trunking though.

You will need to trunk your two switches together. Then trunk the router to one of the switches. Subinterfaces on the router will do the inter-vlan routing. It's usually referred to as a "router on a stick".
