It's just Matthieu's rebased 2.6.32 patchset to 2.6.33 and recipe for it in
OE. You can try 2.6.32 kernel, it's in OE also.

I think, that it depends on flash filesystem you use. I bet TS boards are
flashed with YAFFS(2) or something like this and this filesystem is missing in
OE kernel. I use JFFS2 for example.
Maybe you should try to build minimal JFFS2 image with OE and flash it to your
board, it should work.

I've used some USB CDMA/GSM modem and it worked fine for me, just search for
one which works fine in Linux, usually it's just some RS232->USB converter
which you can use as like any serial device in Linux. I've used it just with
PPP on ts72xx and it was working fine.

Why you need 2.6.28 for 24-bit ADC? It should work with any kernel, but you
need to port or write the driver for it. Maybe if you give us more details
about the device, somebody could help you.

It depends on your skills and experience, so it's hard to guess :-)
