Hi Eric,

There really isn't anything you have to do to use a crossover cable between 
two hosts, just ensure it's really a crossover cable and your using the 
correct cable for the scenerio!

To roll your own:  http://www.makeitsimple.com/how-to/dyi_crossover.htm

If I understand your scenerios correctly:

Host1 (192.168.0.2)<>(192.168.0.1)Router(192.168.1.1)<> Host2 (192.168.1.1)
	Pinging from either Host to the Router--Works using a crossover cable

Host1 (192.168.0.2)<===> Hub <===> Host2 (192.168.0.3)
	Pinging from Host to Host through a hub--Works using a straight-through cable

Host1(192.168.0.2)<>(192.168.0.1)Router(192.168.1.1)<> Host2(192.168.1.1)
	Pinging from Host to Host through the router--Doesn't work using a crossover 
cable?

Is your Router a Linux router or other (i.e., Cisco, 3Com, etc)

For a Linux based Router, look at your documentation to enable IP routing and 
if a Cisco router make sure you have ip routing enabled (i.e., 
"router(config)#ip routing"
