I am not sure if a new bug should be started but this is related I think.
(Hardy) I have a LCD Acer x193w ATI radeon 8500LE (R200)
Both during boot and shut down I get a floating message "input not supported"
BUt Ubuntu does loads
I just switch my drivers to ATI as the Ubuntu howto shows to do it fixed the Xorg
Now in addition to the input not supported I now also have a green screen just before Ubuntu LOads up.
What I am told it is due to refresh rate that problems but I loaded the figure recommended in the booklet from acer?
Hopefully this problem will get fix it seems to be happening left and right...
