[LAU] does a pci-e x1 to pci adapter work with Linux soundcards and existing drivers?

I'm just curious if something like this will work with Linux audio cards? http://www.beaglesoft.com/pcie2pci.htm ///////////////// PCI Express to PCI Adapter featuring PLX Technology PEX 8111 PCI to PCI Express bridge PCI Express x1 cards have been scarce since the introduction of the bus several years ago. We now offer a PCI Express x1 adapter for server or desktop PCs that converts PCI Express x1 bus to PCI. The adapter utilizes a PLX Technology PEX 8111 PCI to PCI Express bridge chip. It will accept standard or low profile PCI cards. As a generic PCI to PCI Express adapter it should work well with most PCI cards. This adapter allows you to use your existing PCI cards in the PCI Express slot of your mother board. It can accept one of the half height cards designed for 2U server chassis environments, such as a Fire wire or Gigabyte Ethernet card. The 32bit 33MHz adapter’s 4 pin connector is connected directly to the power supply of your PC. The heat generated by the card is very low. The adapter has a bracket with a large gap to allow you to plug things into the card. The adapter will also accept a full height PCI card if your case has the extra headroom to accept a higher card. ///////////////// the above cards, however, seem overpriced given they're available for about $28.00 w/ shipping from Hong Kong: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220652485942 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320574364611 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220595038826 Niels http://nielsmayer.com PS: one useful additional feature such cards might provide -- since the pcie x1 riser uses an ATX-style 12&5v power connector, that means you could use a separate power supply from the main computer's to help isolate the analog section from computer noise.
