It seems that this has already been done.  Despite what the docs
indicate, the default currently is not to use the rtc, and no need for
it.

Title:
  use modern hrtimers

Status in MPlayer: a versatile and fast multimedia player:
  Unknown
Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Fix Released
Status in “mplayer” package in Ubuntu:
  Fix Released

Bug description:
  Mplayer prefers to use the old /dev/rtc device to generate high
  resolution interrupts for it to wait on for timing purposes.  This
  interface can only be used by a single task on the system and is
  wasteful of cpu and power.  When this is not available, or not
  configured to allow setting 1024 interrupts per second ( it isn't by
  default ), it falls back to wasteful busy waiting.  It needs patched
  to use modern posix timers that can use the modern tickless and HPET
  kernel features to allow the cpu to remain in deep low power state
  until the exact time requested.
