regardless of all the stuff i'll say about linux being broken, the
stuff in mplayer is horribly broken too. here is the contents of
osdep/kerneltwosix.h:

----------------------------------------------------------------------
#include <linux/version.h>
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,5,70)
#define __KERNEL__
#include <linux/thread_info.h>
#include <linux/list.h>
#undef __KERNEL__
#endif
----------------------------------------------------------------------

as you can see, it #defines __KERNEL__ which is only supposed to be
done for KERNEL-INTERNAL CODE! it also includes headers that are
seemingly irrelevant. i have no rational explanation for why crap like
this should be included in vo_fbdev... :(
