Skylake support on Linux Slackware

I have just bought new server with skylake processor version: E3-1275V5 which I cannot get to work with media on Slackware.

I see that drivers for skylake GPU is included in kernel version: 3.19, but media encoder installer says that it needs kernel 3.14.5 to properly work.

What can i do to fix that is there any custom drivers which I can compile on kernel 3.14.5 and that will work with gpu drivers on my skylake cpu.

Thank you.
