Don't know exactly what info you need for NetBSD, but here is for 4.4bsd.
You want 21 sectors/track, 9 heads, 1572 cylinders, 3600 rpm, interleave
of 1, and 0 for everything else (except partitions of course :-).

For reference, this is from hp300/dev/rdreg.h:

/*
 * Several HP drives have an odd number of 256 byte sectors per track.
 * This makes it rather difficult to break them into 512 and 1024 byte blocks.
 * So...we just do like HPUX and don't bother to respect hardware track/head
 * boundries -- we just mold the disk so that we use the entire capacity.
 * HPUX also sometimes doen't abide by cylinder boundries, we attempt to
 * whenever possible.
 *
 * DISK         REAL (256 BPS)          HPUX (1024 BPS)         BSD (512 BPS)
