I noticed this never got applied.  There was some feedback which I did 
not include in this patch because I think it is inappropriate to touch 
code outside vmi.c at this point for 2.6.21.  Please apply; this patch 
is needed as a bugfix in 2.6.21.  An updated version for 2.6.22 will 
come later which has a nicer interface.
