Well, it's a laptop (HP DV6-6003EG). I recon that getting 100% the
same setup will be difficult. However, since the uPD720200 was/is
very popular, it should be very easy to find one. [It's probably
on all of these "10 euro usb-3.0 pcie-adapters". So as long as you
got a free 1x-pcie port you should be good.]
Here's the lspci summary:
