[PATCH] to fix 2.5.36 MTRR for X (Was: X freezes and input problems)

From: Kari Hameenaho (khaho@koti.soon.fi)

This patch fixes MTRR for me, restoring the mtrr_add_page() old return value behaviour that X seems to need.

The input problem (mouse pointer jumping) seems to be in sylpheed only, so it is application problem.
