I am the pcsc-lite maintainer.

The only PC/SC implementations I know are:
- Microsoft winscard
- pcsc-lite (with some custom versions from Sun and Apple)

Does rdesktop support other PC/SC implementations?

The way the handle are generated is not important as long as they can
be stored in a 32-bit integer. And I think that is the case for
pcsc-lite since a long time now.

Can you point me a version of pcsc-lite that does not store a handle
in a 32-bit integer?
