Not sure if you're aware of this but every time you run Xautoconfig it writes another XF86COnfig file and moves your existing file to XF86Config~ or somesuch.

For anyone that has a new world machine I would suggest obtaining a ppc port of Knoppix/Debian GNU Linux: 
http://www.bouissou.net/knoppix-mib/doc-html/knoppix-mib.html

It has all sorts of tools- it's a complete recovery tool and a complete graphical desktop environment from which to work.  I don't know how well it supports Mac file systems.   It does have very good hardware detection on the x86.  I cannot vouch for the Mac port but it is reported to work.  I commonly use it on x86 boxen just to write an XF86Config file.  Simply boot the disc and if you make it to a graphical environment then your xserver has been configured correctly.  Then copy /etc/X11/XF86Config-4 to your hard drive and use it for yellowdog.  Of course you'll need to make a few adjustments but they should be rather simple.  Font paths perhaps?  Be sure to read the docs on how to boot it as it accepts a rather long string of boot parameters should you need them.

For multiple video cards have a look at Xinerama at

and don't forget

The module for firewire is ohci1394 so..

sudo modprobe ohci1394

(or become root if you are not yet part of the sudoers group)

Not sure if it would show up on the SCSI BUS or not.  You can find out:

cdrecord -scanbus

Add ohci1394 to the list of modules to be loaded on boot.  Then after reboot issue:

dmesg | less

Your drive should show up (I think). HTH

If there's a better driver for your video card than the generic frame buffer (fbdev) then put it in /etc/X11/XF86Config-4.  Get the horizontal and vertical refresh rates for your monitor and enter them into XF86Config-4 as well.  It might be possible to find out which monitor that IS listed comes closest to yours for the refresh rates.  They do not have to be exact matches.  If your actual href is 40-100 then 50-90 should be ok for example.  Just keep it "inside" the manuf. specs for your monitor.
