Kernel built from -current supped today, May 12.  System startup dialog 
does not indicate that _any_ grf<n> devices were configured.  Needless to 
say, X (the B&W version) doesn't run too well without any grf's :)

Also, I tried booting the newest color-X kernel (GENERIC #8, dated May 
9), and it just completely hangs after displaying the message "nubus0 at 
mainbus0"  (by hang, I mean you can't even use the panic button to cause 
an NMI to enter the debugger).

System configuration:  Mac IIci with lots of disks, 24MB memory, with 
E-Machines Futura-SX 24-bit QD video card (set to 1-bit depth before 
booting MacBSD).  Internal video exists, but there's no monitor attached 
to it;  the only monitor is on the -SX card;  startup dialog correctly 
indicates that there's no internal video.

And, the grf section from my config file (continuations inserted by me 
for readability):

	config		netbsd	root on sd1 \
			swap on sd1 and sd2 and sd0 and vnd0 \
			dumps on sd0b

	nubus0		at mainbus0

	grf*		at nubus0

	ncrscsi0	at obio0		# SCSI NCR 5380

	scsibus0	at scsi0
