Yes, I realized this very sadly today. Intel 6300 WiFi adapter isn't recognized, the crap
of Laptop rejects starting firmware and I get a message telling me using uncertified
hardware. Last time I bought a Laptop from Lenovo!

There are lists, but they are outdated and newer chipsets aren't listed. 

There are also some bad hacks changing the PCI ID of the new mini PCIe card to be
recognized by the EFI, but this seems to be very, very difficult to me.

The notebook is now running Ubuntu 14.04. WiFi is recognized by the Linux natively as
well as I can use the nVidia graphics of the notebook. Also the built-in Realtek NIC,
which doesn't work properly even under FreeBSD 11.0-CURRENT as of Friday last week (the
NIC is down until it is switched off and on manually), is working as expected.
