In both cases, the same blanking code gets invoked in the kernel. This code invokes the ``backlight-off'' method from Open Firmware to (as the name suggests) switch off the panel backlight. Apparently on your system, this causes the opposite effect, and unless there is some form of firmware upgrade available for your machine, I'm afraid there is nothing that can be done at the OpenBSD level.
