Could this be done from the kernel, updating the appropiate disklabel
in memory only each time it boots up? (of course, with a bit of
programming :)

Well, after trashing FreeBSD's disklabel I decided to go and reinstall
everything. I deleted all slices from that disk (wd0) and installed only
Win98 and FreeBSD. So the only partition that is not inside the disklabel
is the Win98 one (and I don't need access to it from NetBSD).

I've created now the /home partition (the one I want) inside the disklabel,
so I hope NetBSD won't have any kind of problem :)

Thanks! (I'll try this later)
