Xorg configuration fails on G4 Powermac

I'd like for it to be noted that the cards aren't working properly. The Open Firmware"BIOS" path is incomplete. This has been noted on the freebsd-x11 and xorg mailing lists along with the freebsd ppc mailing list. 
I have tried all options offered to me with none working.
please let me knw which individuals that I need to file a bug report- or multiple bug reports to- on these mailing lists.
Thank you.

Can I suggest adding a "Virtual 1280 1024" (sized appropriately) to
each 'SubSection "Display"' of each 'Section "Screen"'.  I ran into
some wierd problems with multiple screens and found that the virtual
size isn't correctly initialised unless it's explicitly specified.

That said, I suspect that the underlying problem is:
>(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support

ISTR, there is no longer any support for multiple video cards in
FreeBSD - I believe Xorg7.4 relies on external functionality that
FreeBSD doesn't have.  Can you try removing one of the
screen/device/monitor sections and see if it works?
