Hi,

AFAIK you must say "y" or "m" to "CONFIG_NVRAM" when configuring your
kernel to get these buttons working. Perhaps it's already compiled as a
module in your kernel, and you can simply do a "modprobe nvram" do
enable it. I also use the Debian package "tpb" which provides an on
screen display when these buttons are pressed. I don't know though if
these buttons are supported on a R40e; I own a R40.

HTH,
Nils
