Hm. I had to kldload radeon.ko to get the dri sysctl tree first.

drm0.vgapci0.pci1.pcib1.pci0.pcib0.acpi0.nexus0.root0
drm0: <ATI Radeon RV280 9200> [tentative] on vgapci0
vgapci0: Reserved 0x10000 bytes for rid 0x18 type 3 at 0xf8030000
vgapci0: child drm0 requested pci_enable_busmaster
info: [drm] Initialized radeon 1.29.0 20080528
drm0: <ATI Radeon RV280 9200> [attached!] on vgapci0

then I set hw.dri.0.debug=1 and did startx.
