Deal 24,795,893 is still (technically) intractable!
I had a bug in my duplicate-move routine when I wrote that it
couldn't be solved. My solver (at that time) erroneously thought it
had tried all possible moves. Sorry!!!
My current solver stops after 10M nodes and reports that it was never
able to move the 9D or the TS.
Since these two card are at the bottom of the first two columns and
one is needed in order to move the other, I suspect there isn't a
solution to this deal.
Having both red eights over the 9D and the 7S over the TS, lends
further support to it not being solvable.

Speaking of intractable deals, WKRfresno and I have been
corresponding on solving 8x0 deals.
I currently have a list of 250 intractable 8x0 deals from my solver.
Below are the first ten -- in case anyone feels masochistic.
