Bug Description
The utouch-geis test suite fails when packages are built in a PPA because geis_new() is segfaulting. It turns out this is because geis_new() is using the epoll_create1() function internally, which was not introduced until kernel 2.6.27, and PPAs run kernel 2.6.24. The segfault results from an error in the failure path for this situation.
The failure path must be fixed and the epoll_create1() call replaced with the older API available prior to kernel 2.6.27.

For future reference, the utouch stack won't work on a kernel older than 2.6.31. Geis can still attempt to operate on an earlier kernel, it just won't do anything.
Sorry if there's anyone disappointed by this :).
