A quick question; is this only for amd64, or is it also for i386?
(I notice the file is part of the i386 subdirectory)

I have a laptop (runs FreeBSD / i386) which works ok with the internal
drive, but refuses to boot from an external (usb) hard drive [1].
I wonder if this fix would help with this problem...

1) The problem is hard to debug, because as soon as I try too boot a
FreeBSD partition off a usb hard drive, the screen starts scrolling
what looks like register dumps (hard to tell, it rolls by too quickly)
in an endless loop.
However, I have no problems booting NetBSD or OpenBSD from other
partitions on the same hard drive.
