Missing /dev/agpgart

[Alberto Rizzi]

I have a motherboard with a via PT880 and an agp video card Radeon 9600XT

I'm using 6-STABLE with "device agp" in the kernel configuration file
but the system doesn't create /dev/agpgart device

#dmesg | grep agp
returns nothing

#kldstat -v | grep agp
		385 pci/agp_ali
		386 pci/agp_amd
		387 pci/agp_amd64
		388 pci/agp_ati
		389 pci/agp_i810
		390 pci/agp_intel
		391 pci/agp_nvidia
		392 pci/agp_sis
		393 pci/agp_via

#pciconv -lv
is at the end of the email

When I start the X server (both 6.9 and 7.2), radeon and drm modules get
loaded but there are errors in Xorg logs about missing /dev/agpgart

While Xorg is starting, I see these messages in /var/log/messages

May 26 15:02:24 hansolo kernel: error: [drm:pid877:radeon_cp_init]
*ERROR* radeon_cp_init called without lock held
May 26 15:02:24 hansolo kernel: error: [drm:pid877:drm_unlock] *ERROR*
Process 877 using kernel context 0

Xorg works without other problems, but without agp I can't use drm and
2D acceleration, but I have /dev/dri/card0


How can I solve the problem?
