I found this:
http://web.inter.nl.net/users/be-hold/BeOS/NVdriver/
http://svn.berlios.de/viewcvs/haiku/haiku/trunk/src/add-ons/kernel/drivers/graphics/nvidia/
http://svn.berlios.de/viewcvs/haiku/haiku/trunk/src/add-ons/accelerants/nvidia/
They seem to have support for 'coldstarting' the card, isn't it what is
needed to wakeup the chip? (i really know next to nothing about this
stuff :-( (they also seem to have some 3d accel but that's another
story).
Greetings.
