Seems so. I can reproduce a garbled X-Screen at will: starting
the X-Server without redirected /dev/console results in a messed up
screen (looks a bit like only every 8th bit is under the control
of the X-Server).
Starting the X-Server with redirected /dev/console (currently with
xconsole running via network display) produces these messages
WARNING: converted MAP_PRIVATE device mapping to MAP_SHARED (pid 386 comm 
Xamiga)
WARNING: converted MAP_PRIVATE device mapping to MAP_SHARED (pid 386 comm 
Xamiga)
on the now redirected consol window and gices a functioning X-Screen.

Hardware: Amiga 3000 Desktop, CyberStorm MKII 060, Picasso IV.
Software: Netbsd 1.4.
