So I got a new Lenovo G50.
I found all the required drivers in kernel itself. Seems to be quite Linux
friendly so far (not installed desktop yet).

There's one problem though. The kernel module ideapad-laptop which
apparently recognizes the hotkey stuff, backlight and some other things
doesn't let me use wireless. rfkill shows it's hard blocked. Is there any
way to change this?

Some Google results tell me that this is related to the WiFi toggle via
windows. The machine never contained windows ( I bought it with freedos).

I'm not comfortable with opening it to remove CMOS battery as suggested by
yet another Google search result.

What does 'rfkill enable wlan0' give you?  It should be able to override any 
hotkey setting.

The soft block gets removed, but hard block remains, and there's no
hardware switch for the same. If I remove the module it works without any
problems.

I don't really understand the exact purpose of that module. Touchpad,
brightness control, sound control, camera, radio everything works out of
the box without the module. Except that I'm not able to toggle airplane
mode using the hotkey, but that's not a big issue.

I am not familiar with that module.
But in a long distant past I wrote a module to handle the special keys on an ASUS laptop which were exposed via ACPI. 
I always assume these modules add support for special keys and settings not handled by any other driver.

Yes, a quick scan through the code told me that. But I still don't
understand why radio gets hard blocked when the module is enabled and
works perfectly when the module is not loaded. I found this bug today -
https://bugzilla.kernel.org/show_bug.cgi?id=56381

So I guess, it's just a matter of time. Wish I knew kernel coding to
supply a patch.
