Thanks for your response.

The panic is fixed after your patch was applied, and after kldload i915
module, I get:

agp0: <Intel 82855GME (855GME GMCH) SVGA controller> on vgapci0
agp0: unknown memory configuration, disabling (GCC1 14)
device_attach: agp0 attach returned 22
drm0: <Intel i852GM/i855GM GMCH> on vgapci0
error: [drm:pid1944:drm_load] *ERROR* Card isn't AGP, or couldn't initialize AGP.
device_attach: drm0 attach returned 12

Best regards
