What works for you, in-maemo and jschan on a Motorola Xoom doesn't work for me on another device with a different Android version. Is that so hard to understand ?

I have yet to see, here or elsewhere, someone saying (and explaining how) they succeeded in tethering their Samsung Galaxy Tab, running good old Froyo 2.2, to a phone, using USB or BT, DUN or PAN.

Xoom, yes, Archos, yes, something or other called a Q5, also. But not the SGT. I'm just surprised that Samsung managed to shackle a Linux-based system to that level, when Maemo-based tablets have been doing this out of the box ever since the 770 and its "prototype" OS2005...
