 Perhaps this is some help for those struggling with the Intel
 82845M (845M GMCH) like systems. Note that I have an USB keyboard
 and mouse connected to this system.
 
 I did the: # portupgrade -rf libxcb
 
 /usr/ports/UPDATING:
 > Add Option "AllowEmptyInput" "off" to your ServerLayout section
 
 Did nothing for me except caused lockups. Not before or after
 the "20090124: AFFECTS: users of x11-servers/xorg-server,
 sysutils/hal" update.
 
 Pasting only the essentials:

 # USB devices (kb,mouse) would not be otherwise detected.

 # This is left-over from 7.3, I haven't tried without it.

 Probably worth noting that I had to add the following
 lines to /boot/loader.conf:
   drm_load="YES"
   i915_load="YES"
 
 Otherwise drm would fail at startx. 7.3 and DRI worked
 fine without them. I have, however, disabled DRI for 7.4
 since it turned out to be too erratic for my liking.
