As a PCI Express hardware designer I can safely say this is useless (or is a misprint).

There are no 2x lane devices out there. (They are all 1x, 4x or 8x)

No PC's (that I have come across) have x2 lane slots (they have 1x, 4x, 8x, 16x).

99% of non gfx card devices are x1 lane because that is all that is left on a consumer PC after all the "onboard" peripherals are added.

I've had a real problem getting motherboards with anything other than a 1x lane slot.

Maybe if it was an 8x slot wired as 2x then there is a *slim* chance it would work at 2x lane speed with cards which are 4x and above.

Most cards which cannot operate at their intended lane width default to 1x lane.
