After further investigation, OpenATV enigma2 build command - as it is shown in package description - has the following patch + library.
Source: git://github.com/openatv/enigma2.git;protocol=git file://0001-ciplus-vu-hack.patch file://libenigma_dvb_cix.a
Both 0001-ciplus-vu-hack.patch and libenigma_dvb.cix.a cannot be found anywhere.
I also think that distributing a binary of a GPLv2 project, statically linked with a library that is closed source, is against the GPL and thus illegal.

I doubt this will ever be included in OpenPLi. It is against GPL, it is a binary only library linked with GPL code - and I doubt this library is legitimate - most probably it contains keys not signed for VU+ hardware.
