I just tried Xubuntu live cd in case there was an out of memory situation and booted it with the same kernel and the video=ofonly parameter. Both 'startx' and 'startxfce' yields the same SIGSEGV fault in the Rage 128 driver related to the mmio call.
The system doesn't die however so I now got a prompt to play around with and I guess 128 Mb actually is too little for Ubuntu Desktop after all. Maybe a graceful detection of this would be nice instead of a system lockup. For the iMac I continue to use Xubuntu but I will try the Ubuntu-server live cd as well.
