Just a short notice from my side. I finally managed to get the pci
radeon 9200 work, means I can startx.
I had some issues until I found out how to make Xorg recognize the pci
card which is not in the primary pci domain.

I needed this string in the xorg.conf, under the section "Device"

BusID       "PCI:1 at 1:2:0"

Important is ":domain at bus:".

Regarding drm, I get hardlocks as soon as I start glxgears or other
samples. No more info yet.

Here the render string:
---
direct rendering: Yes
OpenGL renderer string: Mesa DRI R200 (RV280 5961) 20090101  TCL
---

Chipset: "ATI Radeon 9200 5961 (AGP)" (ChipID = 0x5961)
Mapped VideoRAM: 131072 kByte (128 bit DDR SDRAM)

Note, it is a PCI card, not an AGP one.

Also, I do run old Xorg (X.Org X Server 1.7.7 and the 6.14.3 ati pkg.).

I'll continue playing a bit.
