I ftp'ed the server and the document and tried it.

machine: Mac IIci w/ Daystar PowerCache.
video: MacII Portrait Video Card. I upgraded its VRAM, so
it can display 16 grays (4 bit/pixel).

They're shown as below in the boot message.

macvid0 at nubus0 slot c: Mac II Portrait Video Card
macvid0: 640 x 870, monochrome
grf0 at macvid0
ite0 at grf0 (minimal console)

My problem is that I couldn't get the grayscale to work.

The new X server works in the b/w mode well as the 1.3 stock
server does.

To enable grayscale mode, I set the monitor to 4 bits
grayscale mode in MacOS, changed the Booter not to touch
monitor configuration before booting NetBSD.

Booted NetBSD, I set the environment variable (I actually
tried the command line argument too.)

% setenv XDEVICES /dev/grf0,2,g

When I start the new X server, the display is split into 16
(4x4) and everything is shown in the most upper 4 screens
same as stock server.  It says that there is no ROM support
in the video card, also.  If you need exact message, I'll
post them later.

Thanks for your cool hack.
