Does this exist...?

A PCIe 16x riser that splits the 16x lane into 2 8x lanes?

I ask because I'm building a server into a 2U rackmount case, and I need 2 PCIe 8x slots on the riser (for the RAID card and a dual gigabit NIC), but the motherboard only has a single PCIe 16x slot (full speed of course). I can't use onboard ethernet since I can't find any mATX boards with dual gigabit ethernet.

I know it's a longshot, but does anyone know if something like this exists?
 
Won't work because it needs 2 PCIe 16x slots on the motherboard; the mobo only has 1 16x and 1 1x, and the cards are all 4x. The only way this would work is somehow splitting the 16x lane.
 
Bumpage since I'm trying to find something quickly. Any clues? :(

EDIT: I know there was a motherboard that had a splitter chip to split the 16x lane into 2 8x lanes, but I can't find anything on the chip itself.

Oh well, it seems like this really doesn't exist. Thanks anyways.

EDIT 2: I found a mATX motherboard with 2x PCIe 16x ports which is exactly what I need, in combination with that riser. Thanks.
