hostapd cannot be run since 2.6.32-042stab112.15

The last version of OpenVZ that worked with hostapd for running wireless access points is Linux rh-vz01.webisp.uk 2.6.32-042stab111.12

Since then when starting hostapd I get this error:

nl80211: Could not add multicast membership for scan events: -2 (No such file or directory)
Failed to initialize driver 'nl80211'

>How reproducible:

service start hostapd

>Steps to Reproduce:
1. Upgrade to kernel beyond version 2.6.32-042stab111.12

3.
