Subject: Dual Monitor Problem (G3 B&W, ATI Rage128, XFree86-4.1.0-3d)

Hi, folks.
I'm stuck getting X 4.1 to work in a dual monitor mode on my G3 B&W with a
pair of stock ATI Rage 128 video cards. Everything works fine with only one
video card installed. But, when both cards are installed, X fails to startup
and crashes with a very hard lock-up (sometime requiring me to fsck manually).
One card is installed in slot PCI 1:3:0 (primary head), while the other is in
PCI 1:2:0 (secondary head). The problem is that X fails to recognize the
secondary video card whenever the primary video card is installed. It doesn't
matter if I move the cards around or move the primary card to the standard
(default) PCI 0:16:0 slot.
During boot-up with both cards installed, I notice that fb0 is identified
correctly as an ATI card; however, fb1 is recognized as an OF framebuffer. My
/proc/fb file contains:
0 ATY Rage128
1 OFfb /pci@80000000/pci-bridge@d/ATY,Rage8y
I don't know, but it seems that the fb1 identification may be related to the
X failure.
My XF86Config-4 file contains the following Device sections (generated by
Xautoconfig4 with only Card0 installed and the replicated/edited for Card1):
Section "Device"
Identifier "Card0"
### Available Driver options are:-
#Option "SWcursor"
Option "HWcursor"
#Option "PciRetry"
#Option "NoAccel"
#Option "ShadowFB" "true"
Option "UseFBDev"
Driver "r128"
BusID "PCI:1:3:0"
EndSection
Section "Device"
Identifier "Card1"

I'd really appreciate any help or suggestions.
Thanks much!
Bob
