perf says


  55.13%  [kernel]                           [k] acpi_os_read_port
  26.65%  [kernel]                           [k] acpi_os_write_port
   8.33%  [kernel]                           [k] __next_timer_interrupt
   5.41%  libglib-2.0.so.0.4200.1            [.]
g_io_channel_get_buffer_condition


./perf top -a

so we now know where the cpu power goes - do you have any idea of this?
