A suspended minor chord doesn't make any sense, and doesn't exist in any real sense. Suspended chords are neither minor or major.
The reason? Because in a suspended chord, you suspend the 3rd, and replace it with another note, in this case, the 2nd. (sus2). It is the 3rd that gives a chord it's minor or major flavor. There is no difference between an F#sus and an F#msus.
You might see one written as a mSus, but that would be simply to keep things in key.
