It may not be needed after all :)

AFAIK all PCI slots are connected now to the PCI-E bus with a bridge
like the old PCI-ISA bridge and there's no way around it. Based on
former reading and experimenting with a desktop graphics card attached
to a laptop, I just searched for "external pci slot" and got exactly
what I wanted: The PCI-E to PCI bridge and a sort of riser card. That
means with the proper adapters or surgery, you could use a 1010 with a
notebook.

Just 1 lane of a PCI-E 1.0 bus is already faster than the entire
shared bandwidth of a classic PCI bus so it's certainly not a problem.
YMMV and would probably depend on the quality of that bridge IC. In
any case this seems to require yet more delightfully affordable
Chinese stuff and yet more testing.
