- Adapted and fixed 'noroot-background' patch originally coming from
the Moblin project and enable by default.
- On ia64 the Xserver brings its own PIO functions (inb, outb, ...).
These are supposed to overrule the ones provided by glibc.
Unfortunately this doesn't seem to work under all circumstances.
Therefore use inX/outX_ia64 and set appropriate defines.
- Fix SIG11 on VT switch when using SW cursor with RandR (bnc #592614).
