Problem with Enabling DRI

[Stevan Tiefert]

Hello list,

I tried to enable the nice composite features of KDE on my workstation. 
It seems they work, but very slow. The KERNEL contains "device 
agp", /boot/loader.conf contains "sis_load="YES"" and that are some 
interesting outputs:

"dmesg | grep drm" outputs:

drm0: <SiS 630> port 0xa000-0xa07f mem 
0x88000000-0x8fffffff,0x80000000-0x8001ffff at device 0.0 on pci1
info: [drm] AGP at 0x40000000 64MB
info: [drm] Initialized sis 1.1.0 20030826

"grep EE /var/log/Xorg.0.log" outputs:

	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) SIS(0): [dri] DRIScreenInit failed. Disabling the DRI.

"grep failed /var/log/Xorg.0.log" outputs:

(--) SIS(0): CRT2 DDC probing failed
(II) SIS(0): [drm] drmSetBusid failed (6, pci:0000:01:00.0), Permission 
denied
(EE) SIS(0): [dri] DRIScreenInit failed. Disabling the DRI.

"uname -a" outputs:

FreeBSD vagabund.w33 6.2-RELEASE FreeBSD 6.2-RELEASE #1: Sat Jan 20 
10:31:01 CET 2007     root at vagabund.w33:/usr/obj/usr/src/sys/GENERIC  
i386

It seems that drmSetBusid causing problems, but I don't know how to 
resolve it. Any ideas?

With regards
