graemem of The Samsung Netbook Community forum hacked his NC10 to add a second PCI-e slot for a Broadcom HD decoder card for 1080p HD playback. Since the mainboard already had the holes and wiring for a second PCI-e port, it was pretty much a straightforward process. graemem however had to deal with potential issues such as the BIOS not recognizing a second PCI-e device but in the end everything worked as Graeme hoped.
