Wow, extremely interesting.  =)  I never knew I could do that. (or how,
for that matter).

This is what I came up with (running this as root because normal users
do not have priviledges to wskbd0/wsmouse0):

 15104 xinit    CALL  fcntl(0x3,0x4,0x4)
 15104 xinit    RET   fcntl 0
 15104 xinit    CALL  read(0x3,0x7fffe6b8,0x8)

 15105 Xmacppc  RET   __sigaction14 0
 15105 Xmacppc  CALL  write(0x2,0x7fffdff8,0x15)
 15105 Xmacppc  RET   write 21/0x15
 15105 Xmacppc  CALL  write(0x2,0x7fffe078,0x10)
 15105 Xmacppc  RET   write 16/0x10
 15105 Xmacppc  CALL  write(0x2,0x7fffdff8,0x1)
 15105 Xmacppc  RET   write 1
 15105 Xmacppc  CALL  __sigaction14(0x17,0x7fffe648,0x7fffe668)
 15105 Xmacppc  RET   __sigaction14 0

I don't know what most of this means.  I assume that X is looking at
/dev/ttyE? for something or other and doesn't find it configured (which it
won't because the only terminal I have on is 'console').  I am booting
with a serial console, so...I figured it would be best just to use
'console' instead of some other terminal.
