Hi everyone!
I wonder if there is a way to dynamically reduce the clock speed of ATI/AMD gfx cards when the system is running in text/console mode. Under Linux, there is a kernel module called "radeonfb" which does the job, but I could not find an equivalent for FreeBSD.
Under X, everything is alright with radeon "dynamic clocks"- but I want my system to start up in console mode and my ATI HD4670 sucks 20W+ if it's not throttled, which is simply intolerable for a "low power" system.
Average IDLE power consumption :
Win7 - 52W
Linux - 66W
FreeBSD - 74W
.. not too much, but FreeBSD is waaaay behind and I want to keep it as low as possible as our bloody local energy supplier raised the prices again- System is Intel E8500/3.16Ghz, Sapphire HD 4670, 4 GB RAM, 2x SATA HD, 1x IDE DVD/RW)
