 With recent updates to "native" Xorg in -current, including the r128
 driver, I updated my affected i386 system with the 201608260900Z TNF
 snapshot build.
 
 If I understand correctly, the TNF snapshots build the newer drivers, but
 the older (v1.10) server.  I don't know if this is expected to work.
 
 Starting X with:
 
   $ X -retro &
 
 switched virtual terminals, but never produced any display.  It then
 became clear that the machine had panicked.  As the machine was
 semi-diskless (swap, /tmp, and auxilliary fs on local disk), it saved
 a crash dump.  Upon reboot, the Xorg.0.log file was 0 length and the
 following backtrace was obtained via 'crash':
 
 1025 [sysop@verthandi:/var/tmp]$ crash -N netbsd.3 -M netbsd.3.core
 Crash version 7.99.36, image version 7.99.36.
 System panicked: trap
 Backtrace from time of crash is available.
