Installing X on netboot client

Can anybody help me to find any information how to install and configure X
on diskless NetBSD/next68k.

I've downloaded and installed all x*.tgz sets from  NetBSD/next68k-1.5.2.
but it doesn't seem to include the X server. It's interesting to see what
the performance will be like with 32 MB RAM on mono slab. Have anybody tried
to run it? Is it usefull at all?

Thanks,
