Cool.  Well, I tried it last night, and after detecting the drive, the
system seemed to time out and then fail, asking me for a device to mount as
the root partition.  I was going to copy the source for the kernel, patch
it, and rebuild, but if that is not the problem, I won't bother.

Let me know what else I can do to help, such as giving any interrupt info
from my running FreeBSD system.

I guess what I don't get is why there is a difference between the two?
