To my surprise, connecting the Galaxy Tab 2 via cable to a PC and using Samsung's much improved Kies did permit the upgrade.
And then locked me out of the tablet entirely, demanding a decryption password at bootup ... although the tablet wasn't encrypted. Oops. A left-over, to be sure, from the botched encryption job I did when I first rooted the tablet. Heh heh. Titanium Backup Pro to the rescue!
Now all upgraded, programs and data restored, encryption working quite correctly at last, and Swype not being quite so much of a performance hog as before!

I'm guessing that it is the CF-Auto-Root which is causing the upgrade to fail.
What is the process for upgrading a CF-Auto-Root'ed Galaxy Tab 2 7.0" from 4.0.x to 4.1.x?
