While you are doubtlessly right for NetBSD, you wrote ``*BSD'' and are
wrong with this: FreeBSD can handle multiple slices with the 0xa5
signature, but it will boot only off the first one.

Of course, there's only limited sense in doing this.  The only
situation i can think of where this is to be _enforced_ is if your
disk requires bad144.  Then it's the only way to restrict the first
slice (where the root partition and thus the kernel is located) below
the BIOS-ficticous cylinder 1024.  Since bad144 places the bad sector
table at the end of the slice (i'm not sure whether NetBSD has changed
this), loading the kernel file could require accesses to the bad144
table, so it must be in the BIOS-visible area of the disk.
