I'll throw this here. I'm pretty sure that this is a Burn-In Test card. It was used in pre-release to see how a DS would fare in strong-use conditions.
This was also used to see how the DS aged (hence the name "Aging card") and the eventual problems that could've arisen from that.
So this isn't the DS's Holy Grail, sorry.

I hope a temper doesn't get it as the average board member here probably doesn't have the hardware or experience to do more than just pull the out of the DS and run the dumper homebrew. This could very easily damage the electronics on the cart.
This really needs to go into the hands of someone who actually has access to an electronics lab at home/work and can actually investigate the internals of the cart. I would guess this cart would have more hardware available to it to allow for debugging and storage of games such as extra RAM, an EEPROM and maybe an FPGA as a controller. All these things wouldn't be dumped by your average homebrew software and could also be damaged by inserting/removing the cart from a DS while switched on.
It could also be that it includes an FPGA or another microcontroller that can communicate with the DS to put it into debug mode. This would really need someone with a good knowledge (at least degree level) of electronics to analyse.
BTW, it's just a plain cart with some flash memory on it, which stores the aging program:

And here I go, I just killed whatever anticipation could've been for this cart
