I've done some additional testing.  Here are a few more unexpected results:
For example: "partnew (hd0,0) 0x0F 2056320 158019120" writes "1021" for end
cylinder
For example: "partnew (hd0,2) 0x0C 116575200 36136800" writes "1021" for
begin & end cylinder
For example: "partnew (hd0,3) 0x00 0 0" writes C/H/S 0/0/1 thru 1021/164/4
For example: "partnew (hd1,2) 0x00 0 0" writes C/H/S 0/0/1 thru 830/164/4
{(hd0) has CHS 10587/240/63.}

Just a hunch, but it seems that partnew cannot write a begin or end cylinder
larger than the largest allowed for that drive minus 2.

I don't know if it matters in actual practice, but "partnew (hd0,3) 0x00 0
0" should write C/H/S 0/0/0 thru 0/0/0.
