    I'm not sure I can fix these without actually duplicating the 
    environment, which in your case I guess means getting a USB CD.  I
    will pick one up the next time I'm in CompUSA or BestBuy.

    I will do a run-through of some of the FreeBSD boot code to try to
    pick out bug fixes but it's unlikely to solve the reported problems.
