* suspend - make sure suspend/resume keeps us on the same state
*
* METHOD
* Set a mode, assert FBC is there, suspend, resume, assert FBC is still
* there. Unset modes, assert FBC is disabled, resuspend, resume, assert FBC
* is still disabled.
*
* EXPECTED RESULTS
* Suspend/resume doesn't affect the FBC state.
*
* FAILURES
* A lot of different things could lead to a bug here, you'll have to check
* the Kernel code.
