Holy 1995, Batman!  The XF86Config file supports doing stuff like you're 
describing, but I haven't seen one in use in ages -- indeed, I'm not 
even sure they *can* still be used.  But X -- always assuming you're 
using X -- did support specifying things like horizontal scan rates, and 
I assume still does behind the scenes somewhere.  But Lordy, I hated 
tweaking the modelines by hand.

This page does mention some things (e.g., pointer devices) that I *have* 
used in recent memory, so maybe this stuff is still viable:

Good luck!
