Unfortunately, due to either a mistake on my part or a spiteful Makefile, /boot/kernel.old/ is totally gone. I wish it wasn't, otherwise I'd be able to look at the contents of my root partition more carefully. As you suggested, /boot/loader.old works almost as well as /boot/loader but the old version doesn't allow me to load/unload modules like I can with the new version. But it doesn't matter whether I'm using /boot/loader.old or /boot/loader. As soon as I have /boot/kernel/kernel loaded into memory and tell it to boot, the "-\|/" twirley spins for a fraction of a second, freezes, and the computer powers down a few seconds later.
Unless I can figure out how to successfuly mount and run the userland on my root partition by way of the kernel from a 2 month old install CD or a cross-built kernel, there isn't much else I can do.
It's worth mentioning that this notebook needs a small patch to address compatibility problem with the keyboard (it's in GNATS) so that the first probe won't cause it to reboot. I also compiled out ACPI, which has never worked right. Up until now, however, the notebook booted up ok otherwise.

Any further information you can provide would be appreciated. For
example, do any kernel messages appear before the freeze? What does
"lsmod" from the loader output, and I presume you've tried booting
kernel.old ("unload", "load /boot/kernel.old/kernel", "boot")?
You could also try booting with the old loader by interrupting the
boot process by pressing a key immediately after the first of the
|/-\ sequence appears. You should get a prompt like:
>> FreeBSD/i386 BOOT
Default: 0:ad(0,a)/boot/loader
boot:
Enter
0:ad(0,a)/boot/loader.old
and see if that allows you to boot.
