So that's a 1st generation iMac with an ATI Rage II on the mainboard - 
you may want to look for a VRAM module, standard video memory is only 
2MB which s rather limiting, with such a module you can have up to 6MB 
which would allow 1024x768 in 24bit.
The only real catch with X on this hardware is the monitor - it needs a 
fixed horizontal frequency of 60kHz. Just do X -configure, this will 
put a mostly working XF86Config into your home directory, then add 
'HorizSync 60' to your monitor section. With this X should come up in 
1024x768 at 75Hz. Without this line X may come up in a video mode the 
monitor can't display ( the horizontal frequency needs to be very close 
to 60Hz or it won't sync ). Unfortunately there's no way to identify 
this monitor in X since it doesn't provide any DDC data.

have fun
