My Girlfriend also has a x121e with the same problems, so I replaced her WLAN card. For those wanting to do the same: The trick is to plug the card into the spare mini PCIe slot and not the WLAN card slot. This way the BIOS will not complain about unsuproted hardware. The spare slot is meant for a WWAN/UMTS card, but the WLAN antenna cables reach it just fine. It is really simple to do its just 3 screws for the panel and one for the card, plus the antenna plugs.
I bought a Intel Centrino Advanced - N 6200 card (half lenght PCIe) for about 20€ and it works perfectly. Though I recomend using a full lenght PCI express card as thats what the slot is made for (I had to fix mine with tape, which is a lot mare stable than it sounds). (Sorry if this is of topic for a bug report, but I thought it might help some people.)
