That would certainly explain what I am seeing.   I thought Rento's patch was 
intended to do away with such hard coded addresses, but perhaps not all of 
that is done yet.  An easy test would be to change the range so it matches 
what the 64 bit kernel would use.   What address range should I use instead 
(for 64-bit)?
