The latter seems to be the right way (but you don't have to allocate
such a large area to hybernation).  The easiest way to save
hybernation area of Libretto is executing fdisk.exe from DOS (or
Windows95's command prompt mode), keep FreeBSD partition as extended
DOS slice, and change it to FreeBSD slice later from sysinstall.

This is the FreeBSD "fdisk" result of my Libretto 50 (+ IBM 3.2GB
disk).  10x128x63 sector gap is enough for hybernation area (just 39
megabytes).

******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=788 heads=128 sectors/track=63 (8064 blks/cyl)

parameters to be used for BIOS calculations are:
cylinders=788 heads=128 sectors/track=63 (8064 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6,(Primary 'big' DOS (> 32MB))
    start 63, size 741825 (362 Meg), flag 0
	beg: cyl 0/ sector 1/ head 1;
	end: cyl 91/ sector 63/ head 127
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
    start 741888, size 5539968 (2705 Meg), flag 80
	beg: cyl 92/ sector 1/ head 0;
	end: cyl 778/ sector 63/ head 127
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
