Sleep doesn't work on PowerBook G4 12''

[Janus <ja...@rt...>]

Hi,
  I am trying to configure my PowerBook G4 12'' with debian. The only
thing what I can't do is the sleep functionality.
  On MacOS X it works properly (and very fast), here I can't manage to
get it sleep.
  When I close my lid the apple light turn off, but the machine still working.
  pbbcmd query TAG_SLEEPSUPPORTED returns 0.
  Is there any way to get my laptop to sleep to ram or sleep to disk?
  Please, let me know what information do you need.
  Cheers,
        Janus
