Description of problem: Mac Mini purchased 1 weeks prior to 10.4 release. upgraded to 512MB ram. (40GB HD, no wifi, no blue tooth, 1.25GHz). Installing FC4 PPC (DVD iso) on the system causes the monitor to go into powersave mode (DPMS off) and never restores. I see yaboot load, I type linux <enter> and see the kernel load, and a video switch to another FB mode, then another video switch which causes the the monitor to go into power off mode. (Gateway EV700 17" monitor through apple supplied DVI adapter) I tried linux resolution=1024x768 and linux text And the same thing occurs. waiting does not yeild any change in the state of the system.. I have to force off (holding power button for approx 10 seconds)

What refresh rate is being *assumed*? I know OS X shows a 60Hz and a 120Hz (which 120 causes my monitor to go "off" as mentioned above). but why would the higher be chosen over the slower? I'll post DDCprobe information once the system gets up enough to get me a shell.
