I think it is possible. If you have a router in front of your pix - you can route the second network to your pix external interface and then use the "static" command as usual. I am not sure if I am being clear enough, so here is an example:
You have 2 subnets assigned to you by your ISP - let's say they are 126.96.36.199/24 and 188.8.131.52 /24.
