Anybody out there good with X modelines? I'm doing a fairly fun

monitor. I have it working under DOS using some utilities that rewrite

And I'd like to create modelines for 320x240, 384x224 for starters..

anyone who could help out or point me to a good faq (I've been on
google all morning!), I'll email you a beer!
