From: Ike Panhc <ike.pan@canonical.com> Git-commit: 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a Patch-mainline: v3.3-rc8 References: bnc#745236 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.
