K-lens Matrix metering on a -DS?

[Cory Papenfuss]

	Hey all... I've been playing with some older lenses I've got with 
my *ist-DS, and I figured I'd try my hand at modifying a lens to have the 
electrical contacts.  Basically, the same modification as outlined here:

	After successful completion of drilling jigged divots, I still 
cannot get anything other than center-weighed metering.  Upon further 
examination, it appears that even on an official KA lens with insulators, 
if the aperture ring is set to other than 'A', center-weighed metering is 
used.  Looking through the manual, it says that multi-segment metering 
requires a 'A' lens or greater, but doesn't actually say it must be *set* 
to 'A'.  Is this a limitation in the firmware on this model?  Apparently 
on some bodies (like Mark's) it should be possible once the contacts are 
set to inform the camera what aperture ranges it can do.
