The answer is yes, it should work fine as a regular passme. If ones owns a mk2 or mk3, those acts as passme devices also. I'm getting my supercard soon, and will be using the mk3 as the passme device.
You need a passme2 device, superpass 2, etc. if you want to use it with the ds lite (import only currently), since it has one of the newer firmware revisions.
