Bug#729046: drm failing on kfreebsd i965

[Christoph Egger <christoph@debian.org>]

Hi!

actually:

 13302 glxgears CALL  ioctl(0x4,0xc0106471 ,0x7fffffffc760)
 13302 glxgears RET   ioctl -1 errno 22 Invalid argument
 13302 glxgears CALL  ioctl(0x4,0xc010645b ,0x7fffffffc6c0)
 13302 glxgears RET   ioctl 0
 13302 glxgears CALL  ioctl(0x4,0xc020645e ,0x7fffffffc710)
 13302 glxgears RET   ioctl 0
 13302 glxgears CALL  ioctl(0x4,0x800c645f ,0x7fffffffc730)
 13302 glxgears RET   ioctl 0
 13302 glxgears CALL  ioctl(0x4,0xc010645b ,0x7fffffffc6e0)
 13302 glxgears RET   ioctl 0
 13302 glxgears CALL  ioctl(0x4,0xc008646d ,0x7fffffffc870)
 13302 glxgears RET   ioctl -1 errno 22 Invalid argument

the last one seems to indeed be DRM_IOCTL_I915_GEM_CONTEXT_CREATE .. I
shouldn't rely on kdump actually finding the symbol for arbitrary ioctls
