Lane,
	Did you by chance remove keyboard / mouse support from your kernel?  
kldstat(8) may hold the answers, unless you have the mouse compiled  
directly into the kernel. Sounds like that may be your problem:

msg06918.html>.
	So you could try commenting out the mouse and keyboard references,  
just to see what happens..
	Another solution that you may want to look into as an alternative to  
using xdm is X11 forwarding via SSH.
