[PATCH] APM Screen Blanking fix
- Fix screen blanking on BIOSes that return APM_NOT_ENGAGED when APM enabled screen blanking is not turned on. The original code only tried to set the state on device 0x100, and then 0x1FF, and I added 0x101 to the mix too. - Clean up logic in apm_console_blank(). - Prevent the error message from printing out twice.
