Interesting.  If others care to weigh in, I can either re-write the 
"Advanced Partitioning" section in the HOWTO, or whack it completely.

William, can you give some background on the hardware used for your 
tests?  I'd be curious if this data holds up across various drive types, 
LVM, etc.  (Without trying to exhaustively test all the possibilities, 
that is)
