Well, I tried it, and it apparently works. The trouble is the section:

title NetBSD-noMB
root (hd0,2,a)
kernel  --type=3Dnetbsd /m0 console=3Dpc root=3Dwd0a

in this shape does not seem to pass the root and dump parameters to
the kernel, so they have to be entered by hand (mind you, I had the
splashscreen enabled ... had to reset).

I've had grub with chainloading on this machine (and on two others
previously - the original setup was a few years ago and has been
transfered to two more laptops later, with or without disk change),
but with chainloading; I switched to multiboot around the time it came
about - I believe it to be February this year; the one positive one
can take from this is that one has to be prepared to see strange and
unexpected behaviour when one is running the latest bits of code - but
then, we all know this, don't we?
