hello angus,
I am using Debian/Woody on a powermac 9600/350 with an IMS TwinTurbo
graphics adapter and with kernel image 2.2.20 + xserver version 4.1.0.1
some hints that maybe help you
1. for the 2.2 kernel on a powermac 9600/350 only the first 3 PCI-Slots
are visible for Debian and a update to 2.4.. kernel will solve the problem.
1.1. give Open Firmware the information in wich PCI-Slot your
GFX-Adapter are housing.
here the adresses
PCI-SLOT - Adress
--------------------
A1 - @D
F2 - @F
B1 - @E
C1 - @F
D2 - @D
E2 - @E
so for my TwinTurbo on the first PCI-Slot (A1) the output-device in Open
Firmware looks like this
/[EMAIL PROTECTED]/IMS,[EMAIL PROTECTED]
1.3. for xserver the fbdev-driver is the only one who works for me (but
slow as hell).
the imstt-driver are only correct when in 8-Bit-Mode 15/16/24 bit depth
yields in "psychedelic" color shifts
1.4. some links that can help you

1.5. if you get the IMS TwinTurbo working under the imsttfb-driver with
xserver let me know ;-))
have fun
bye fab
