I've had no time to test settings separately, but setting both sysctls
leads to the same issue as you : a modem-like beep at resume time :/

Also, I sometimes get a black screen when rebooting into the kernel I
have which is known to work (graphics + 3D accel + suspend/resume).
Quite strange, it persists at reboot. The only way I have found is
remove the battery and wait a few hours to be able to start X again...

Best regards,
