    Short answer : "NO, but we hope to work on it eventually".
    Long version:
    BLCR does support 32-bit PPC, which is the first to two hurdles.  The 
    second is the differences in the reduced-functionality kernel present on 
    the compute nodes of BG/P.  We do not expect BLCR to ever run with IBM's 
    compute node kernel.  However, we have reason to beleive that the 
    changes to work with the Zepto OS kernel from Argonne National 
    Laboratories (ANL) will be relatively minor.  I have account access and 
    a small allocation of time on the BG/P development machine at ANL for 
    the purpose of working on this, but have not found the time to devote to 
    the work.
