How to debug Fn-xxx key events?

[Norberto Meijome]

Hi there,

( background : I have a thinkpad z60m, several of the fn-[blue keys]
work, but not all - I would LOVE to be able to detect them via devd
style configurations).

not sure if this is the right list, but since this relates to the magic
FN key found in most modern laptops, i figured I'll start here.

I want to be able to capture Fn-[something_else] key events . I know
that they cannot be detected outside the kernel. is the right place to
work on this the acpi_[brand].c in /usr/src/dev/acpi/ ? 

thanks!!
