Help!

I have searched and searched, and found dozens of various XF86COnfig 
files for iMacs and Macs running any possible Linux variant and even 
some NetBSD. I have tried typing ModeLines and rebooting so many times, 
my face is now a purplish shade of blue.

One message I found from port-macppc from last year was:

which seems to indicate that the problem I'm trying to solve has indeed 
been solved. Emil, or anyone else who has XFree86 working on macppc 
1.6.1, could you please send your XF86Config file my way? I'd be 
eternally grateful!
