Are you running an amd64 build?  I came across the same issue on my
Dell laptop and found the following code in acpi_ReqSleepState:

#if !defined(__i386__)
  /* This platform does not support acpi suspend/resume. */
  return (ENOTSUPP);

I guess that's where the "Operation not supported" error is coming from,
at least on amd64.
