Indeed.  What you can do is use imq and add a imq device to your eth0.  
Redirect all incoming traffic to it and a htb qdisc to the imq device.  
Create 2 classes : one for eth1 and one for eth2.  And voila, eth1 and eth2 
can share 1024 kbps.
You can have a problem splitting the traffic in the classes because you don't 
know the src address when the packets enters your shaper.
