I'm not a fan of jumperless cards in PCs, for the reasons you note.  
But, on the PC, you rarely need to modify those settings once 
configured.  In the situations I am considering, that's just not an 
option.  And, the number of jumpers I would need to include would be 
daunting in some scenarios (a large RAM cart with UART and Terminal 
Emulator ROM)

This is a good idea, and I think I can support this.
