Thanks to Mitch Spector's iMac booting web page, I now have a pure diskless
setup working for this 333mhz grape iMac. (Yes, it does appear to work with
the 333mhz version!).  Of course, some comments...

1. mountd and nfsd are presumed to appear in /sbin, but on i386/1.4.1 I found
	them in /usr/sbin.

2. I edited root/etc/ttys and changed the vt100's to vt220's so I wouldn't
	have to type it seperately for each login.

3. I had to stty erase ^H because the keyboard map for the iMac keyboard maps
	delete to control-H...

4. Don't seem to be having the "infinite repeat" problem on this machine. good

5. If I hold down the N key on powerup, the first thing I see is the NetBSD
	dmesg in "Sun console font"; however when it gets to mounting the
	root device, it finds nothing and prompts for a root device BUT the
	keyboard is dead so I have to power-cycle it. It looks like we depend
	on some console/keyboard initialization that happens when you use the
	OpenFirmware command line to boot the kernel.

6. If I try 'startx' with slightly modified skel startup scripts, I get:

OsVendorInit
X: open kbd/mouse: No such file or directory
_X11TransSocketUNIXConnect: Can't connect: errno = 2
_X11TransSocketUNIXConnect: Can't connect: errno = 2

_X11TransSocketUNIXConnect: Can't connect: errno = 2

giving up.
xinit:  No such file or directory (errno 2):  unable to connect to X server
xinit:  No such process (errno 3):  Server error.

Not sure what device nodes it is looking for. dmesg follows:
