Sony laptops have a single hardware rfkill switch, which controls

My Vaio VGN-TX770P has ipw2200, which IIUC understands hardware rfkill
switch state. At the same time, when there is no wifi network around and
I am on internal GRPS modem link, I would like global switch to be on,
but wifi to be off. The main reason is to save power. The device has a
dedicated key combination for this, on which Windows drivers by Sony
operates.
Please don't add more custom radio control switches. It'd be better to
add rfkill support. Otherwise we have even more stuff in /sys to carry
around for ages before deprecating.
Do you mean that the patch should use some other file instead of
/sys/devices/platform/sony-laptop/wifipower for input/output?
If so, could you please provide some pointers on what should be done,
and where in the source tree to look for references?
