There are MANY reasons Commodore why could recommend against using those 
mysterious holes. Putting them there is a heavy hint ONLY if you
open up the case, voiding the warranty, and if you have sufficient
technical knowlege to know what to put there and how.

In addition to money, consider the following reasons:
  1. The board does not work reliably with memory installed on the
     motherboard, or has not yet been proven to work reliably.
  2. The service centers do not have the information necessary to 
     diagnose and repair problems with the additional memory.
  3. They don't have the resources to support people such as yourself
     that are interested in hacking the hardware.

And, finally, do you find something wrong with Commodore wanting to
make money?  That is what they are in business for, isn't it?  They do
need to make money so that they can develop new products and maybe even
improve their marketing efforts that many people in this newsgroup are so
quick to criticize.
