I can confirm that the rfkill and buttons stuff work well with the
native sony-laptop module in kernel 2.6.30. Given that I decided to try
the nvidia-control module to just disable the nvidia card. Now a strange
thing happens; the power usage is almost the same with or without the
use of the nvidia-control. It is not a fault of that module: the power
usage is almost the same also using Eva's module or the native one (I
always used it since the first installation in my Z21MN). Are we sure
that the nvidia card is really disabled and/or it really use some power
when it is not used?!
