Hello.
Mine is quite the same model as yours : Powermac 2*25. ghz, with ati9600
(powermac 7,3)
With some differences : I've a got a PCI model , not a PCI-X one, and my
radeon is an ati 9600XT 128MB.
Is yours a powermac 7,2 with a 64MB ati9600 ? or a 256 MG card ?
My card is named ATY,Piton (not sure of the orthograph), your is
ATY,SimoneParent in dmesg.
And I've got a running X11 with 3d, but it's kind of sluggish.
The main problem on your side may be that radeon firmware fails to load.
See this on your dmesg :
[ 3.800316] [drm] Loading R300 Microcode
[ 3.800403] radeon 0000:f0:10.0: firmware: failed to load
radeon/R300_cp.bin (-2)
[ 3.800418] firmware_class: See https://wiki.debian.org/Firmware for
information about missing firmware
[ 3.800427] radeon 0000:f0:10.0: Direct firmware load for
radeon/R300_cp.bin failed with error -2
[ 3.800664] [drm:.r100_cp_init [radeon]] *ERROR* Failed to load
firmware!
I remember having this problem after the install that seemed to vanish
later. I've fiddled a lot with different cards, card inputs and monitors.
For instance, I didn't have graphics with a 9800 card and a VGA monitor
plugged with an adaptator in a DVI input, but I had graphics with this
9800 card and a dvi monitor.
I also installed first the Jessie version of amd-graphics-nonfree, and
upgraded later. Now I'm running with the later version.
You may verify that the r300 firmware is in /lib/firmware/radeon/
Maybe you can try to reinstall the package.
And you can remove your boot option about agpmode and see what dmesg
says. My card tries to run in AGP8, I don't know if yours can.
On my side, the firmware loads correctly but the driver fails too "ring"
the card in agpmode and falls back to pcimode after that. This is a bug
that causes the slugginesh of my X11.
I'm curious to see if your card is better supported than mine.
I didn't find this bug in a bug report on the r300 driver and may file one.
