Very similar to my setup then. Are you booting via lilo or elilo?

I'll have to finally tinker with X some tomorrow w/the day off and all. Got 
some pointers from ajax, though it looks like you're already doing what he 
suggested... (imacfb w/fbdev for X)

I'll work on that some tomorrow. Its pretty hefty.

I took a stock 2.6.16.5 kernel and patched in the imac-2.6.16.1.patch from 
mactel-linux.org, also using the 2.6.16 config from there. Same patch applies 
cleanly to the 2080 FC kernel, builds and installs fine, but no love on boot.

It'll be even easier in two weeks, when I'm sitting just down the hall from 
him... (Well, at least on the days when he's working from the office. :)

I'm hoping we'll get some mactel hardware in the office sooner than later to 
play with also.
