I tried this on a T61.
As you say, there are two "rfkill" related buttons on this platform, the
actual rfkill switch on the front and the Fn+F5 buttons. Trying these
out I saw the following (output annotated to be readable - index 0 is
bluetooth and index 1 is wifi). It looks to me like things are behaving
reasonably and I do not see that Fn+F5 changes wifi at all.
Some things I learned:
- Fn+F5 does nothing if HW rfkill switch enabled
- if bluetooth SW disabled with Fn+F5 and you then toggle the HW rfkill
switch you will get bluetooth back.
