    Scrap the old patch, it was still allocating low memory first

    I don't know if this will solve David's issue with twe.  If not
    then hopefully I will be able to track it down when I get my TWE
    card in about two weeks.  I'll also take a quick look at the TWE
    code to see if there is something obvious.
Still no love from the twe driver with this patch applied.... :-(
