Subject: Subject: SM501: Align PANEL fb to PAGE_SIZE
From: Ben Dooks <ben-linux@fluff.org>

Some programs, such as anything linked with directfb get
the drawing wrong if given an screen start which is not
aligned to PAGE_SIZE. Change the allocator to always return
an properly aligned address when asked for PANEL memory.
