WDS questions

hello

i have some WiFi/WDS related questions:

1). Any card with 802.11b supports also WDS?
2). What is needed to transform PC with WiFi card (Prism II) into an
AP/WDS bridge/WDS AP??
3). How is it implemented? Kernel/userspace (on 2.4/2.6 kernels).

(I am trying to modify Linux-based router with "dead" WISP function, so
I must understand how it goes).

4). Not related to others:
there is a PC with Mandriva, kernel 2.6.12. Have inserted Prism II (LG
11Mbps) PCI card in. Module loads (orinoco_cs) but there is NO ethx
interface. Module loads "normally" without any complaints. Where to dig?
(I have same card in 2.6.16.36 box working OK., but there is Fedora Core
Dev.)

W.P.
