Is there a tighter definition of where the hibernation pages go? As
the only real constant of the hard disk is the total number of sectors,
having a definition in units of fictitious cylinders is rather scary..

Based on the above, I think the following does what you want:


LIBRETTO:\
	:dt=ESDI:se#512:ns#63:nt#16:sc#1008:nc#58140:\
	:pa#15175440:oa#63:ta=4.2BSD:ba#8192:fa#1024:\
	:pb#1050147:ob#15175503:tb=swap:\
	:pc#58605057:oc#63:\
	:pd#58605120:od#0:\
	:pe#481950:oe#16225650:\
	:pf#41897457:of#16707600:tf=4.2BSD:bf#8192:ff#1024:


(with the usual health warnings) so adding that to /etc/disktab, and

  disklabel -w -r wd1 LIBRETTO

should do the trick..
