Expansion cards aren't the same kind of "cards" that card numbers refer to.
Springboards are an exception. All others expansion cards are accessed as a
file system rather than a storage heap.

DmGetNextDatabaseByTypeCreator finds databases on all cards.

0 to MemNumCards() - 1. Generally, have a look at the Memory Manager APIs as
well as the Data Manager APIs. The Data Manager sits on top of the Memory
Manager. A lot of functions aren't implemented in both layers. For example,
there's DmNewHandle as well as MemHandleNew, but there's only MemHandleSize.
A lot of applications for Palm OS assume card number zero. This works fine
on most devices, but not on Visors.
