I'm fairly sure that this isn't true, since I was using the HID
drivers as modules for both my mouse and keyboard for a while ('til my
bloody mouse died).

Hotplug is definitely a classy piece if code; I've onyl tried it with
the above mentioned keyboard and mouse, but it certainly detected them
and modprobe the right modules.

I'm not sure if this is neccessary or not, but it does provide some
interesting information. It's not mounted by any piece of software;
it's a normal filesystem mounted by mount(8). I have the following
line in my /etc/fstab:
none /proc/bus/usb usbdevfs defaults 0 0
which loads it up fine. AFAIK this requires the 'preliminary USB
device file system' to be compiled into the kernel.
