[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?

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:


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.
