[lubuntu] imac g3 tried many xorg.conf configs... any more ideas?

g3 slot loading imac flower power
600mhz
640mb ram
airport card

I'm able to boot to yaboot and to my command line... but i cannot get X to start up. Im checking lightdm it doesnt seem to have any errors in the log. My xorg.0.log file is throwing errors for Bus error at a certain locatation [x0xx000000] for example.
It then says aborting x server signal 7 bus error.

I have tried inputting the specs for the imac based on other imac examples. i was able to log in and i edit my setting and hit ctrl+o to save file. I know its saving correctly. i checked the xorg.0.log to see what xorg.conf and it does use 'xorg.conf.new'

I even changed my yaboot parameters to add and tried that...

I even tried booting using yaboot parameter
and all that did was freeze on my open firmware screen before yaboot comes up.

Any ideas?? I reallly want to get lubuntu up and running.. my kids have projects to do for school coming up and i feel really bad that i cant get this thing runng... i dont want to try fedora..
