Hi, man =)
As far as known here, there were some successful Ubuntu installations on Y510. Also it is konwn at the moment that all drivers except videocard (ATI graphics) are the same for Y510 and Y710. So it seems to be OK to install Linux on Y710 - so far nobody reported about any problems with hardware on Linux. Oh, except inverted camera, but this one was solved somehow.
