I've put a shrinked netbsd-4 kernel for hp318 (untested):

(well, 4.0 kernel is much larger than 1.5...)

Note this kernel doesn't have any COMPAT options
so you have to prepare netbsd-4 (4.0_BETA2) userland
binaries on your server.
Snapshot binaries are available on the ftp:
ftp://ftp.netbsd.org/pub/NetBSD-daily/netbsd-4/
