Errors during start of Xorg on 3.9

Greetings!

I installed OpenBSD 3.9 few hours ago and all works fine, instead of X.
I never used Xorg on an OBSD system and generated a new config with "Xorg
-configure".

Following errors appears:

(WW) xf86AcquireGART: AGPIOC_ACQUIRE failed (Device busy)
(WW) GARTInit: AGPIOC_INFO failed (Device not configured)
_XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be
created.
_XSERVTransSocketUNIXCreateListener: mkdir(/tmp/.X11-unix) failed, errno = 2
_XSERVTransMakeAllCOTSServerListeners: failed to create listener for local
...
FreeFontPath: FPE "/usr/X11R6/lib/X11/fonts/misc/" refcount is 2,
should be 1; fixing.

I googled many hours to fix that, found no solution or hint about that. The
permissions on /tmp are correct
and should work for other users (can create files in it). It takes also (~)
10 seconds to start the window manager.

Anyone else that problems? Hints or solutions are welcome! Thanks.
