Hi,
AFAIK the wlan-ng drivers only support prism based cards.

The stock 2.4.x kernels include most of the PCMCIA-cs package and include drivers for both Hermes and Prism based cards.

Prism support is a bit naff though (hence the wlan-ng project) and you can't put either type of card into monitor mode using the PCMCIA-cs drivers :-/.

Also, since wlang-ng v0.1.10 the monitoring code has been (re)included. So there is no need to use 0.1.8 and the patch :-). Latest version is 0.1.13pre1.

If you want to do promiscuous sniffing under Linux get a Prism II based card.

As you have an Orinoco card then you could just get the Wildpackets driver and use it in Windows for promiscuous sniffing.
