...and it does appear their is an "X" as you have found.  Maybe this will be of use. 

I have two questions about your "X" (Checking my theory on the mystery of the location of the "X")
1.) In reference to where your "X" is located to the balancing weights, how would you best describe where it located?
2.) Do I see long stretches of white crayon markers running the length of the shaft from the weights towards the "X"?

Another question:
Do you have other stripes besides the three seen in the center? (Or are those two stripes I see closer to the rear yoke of the shaft a sort of "rub marks" in the rust?)

Almost appears that their are 2 "X"s.  The one next to the white line is very sloppy, almost like they messed up, and the other was directly over the green stripe.  Also appears that both are inline with each other and they are directly between the weights.  Do not see a line that runs the length of the shaft except the seem of the tube.  Their is a brown stripe locate towards the differential end.  Then the 3 in the middle.
Took more pictures, but having trouble getting them to post.  They maybe too large.  I will post as soon as I figure it out.

I have a theory on the "X"'s location...It is in line between the two weight locations on each end of the shaft. I wonder if it is a "beginning point" for the balancing process. The weights on this driveshaft are as follows: Front of shaft has one weight centered on the tube seam. Rear end of tube (has tube in tube design): two weights with edges of the weights lined up with the seam.  The "X" was centered slightly off of the tube seam, towards the two weights (towards the rear end of shaft). Stripes on the shaft are near center of driveline, front stripe is pink, center is green and rear is white. The X is on the rear half of the shaft near the white stripe.

... Also appears that both are inline with each other and they are directly between the weights. 

Your example matches up (like mine) to the "theory" I have of the "X" being a "beginning point" of the balancing. I watched a youtube video of Inland Empire Driveline making a custom driveshaft for an old Mopar and using that video as a source of knowledge of "how drivelines are balanced", I see how THEY balanced the drive shaft. (at about the 12 minute mark of the video)
Seeing how they stopped the driveshaft and said "using the mark", I see how another driveshaft builder "could" have Crayon-Marked an X as a beginning point. I am sure there are other good videos (probably BETTER videos) on the subject of balancing drive lines but I liked how they set this one up old-school ;)

Liked the video...didn't like the lack of jack stands during the measurement process!
