We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.
Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.
Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.

Two modification.
* Check quirks also.
* for static variable, no need to set to 0 as initial value.

Thanks! As described at <http://bugs.debian.org/655941>, without this
patch, Andrey was not able to use wifi, getting the following message
in the kernel log instead:
iwlagn 0000:03:00.0: RF_KILL bit toggled to enable radio.
rfkill list gave
2: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no
regardless of the state of the actual radio kill switch. Unloading
the acer_wmi was a workaround. With this patch, wifi works without
needing to unload acer_wmi, so:
Tested-by: Andrey <andrey.k.p@gmail.com> # Ideapad Z570
He tested against the 3.2.y tree.
When applying this, please consider cc-ing stable@ so people using
point releases can benefit from the fix, too.
Happily,
Jonathan
