As james had presented before, 1.1 is using one hacking method to make it (MT) 
work.
And it is driver specific to make the mtdev (kernel part) work.

I don't think so, it might ask your port in driver for following MT protocol, 
and also need new libmtdev for translating the protocol.

S103t is using cando panel and it works well with new mtev. For 12777, tsc2007 
will only work with evdev for single touch, mtev will not support it.

Can you please tell me the reason on "deliberate"? The panel intended to report 
inverted Y coordinate value up?
I run into some weird issue on NV and RV with tsc2007, even though before the 
upper level inverted the value from lower 
level and seemed works well, but from log of device file, seemed the Y 
coordinate value is right, and anyway, now input driver 
can not make the coordinate value right even with "invertY" option.

Here's how I understand the state of things with touchscreen 
drivers, xorg, and the Cando touchscreen in the Ideapad's:

MeeGo 1.1:

   - 2.6.35 kernel + mtdev driver patch.  The mtdev driver
     would intercept the Cando device, instead of using the
     driver from the vanilla kernel.  There were about 4
     specific devices intercepted/handled by this kernel
     driver.

   - A specific version of xorg-driver-input-mtev
     that is looking for /dev/input/mtev (or something
     like that).

MeeGo 1.1.90.x:

   - 2.6.37 kernel with no special patches

   - Xorg with newer version of xorg-driver-input-mtev
     and a xorg.conf.d file to map the Cando device to
     the Xorg mtev driver.

Getting your wires crossed between the kernel mtdev patch 
and the Xorg mtev driver will mean no multi-touch (and 
sometimes no single touch).

I think a non-mtdev-patched 2.6.35 kernel will probably work 
with the newer Xorg mtev driver (with Xorg.conf.d file).  I 
haven't tried it myself, though.
