no 2.6.35 has the EV_VERSION value corresponding the the ev API of
this kernel version so that's not the right thing to do.

tslib has this commit which triggers the problem by allowing old kernels
to run tslib compiled with newer headers but not the reverse :
https://github.com/kergoth/tslib/commit/412d99d8b92c12545f939972146a38c5074=
f3dcb
so for i.MX53 tslib may need a patch to relax the check.
