I found another card that works: U.S.Robotronics Wireless PC card (USR022410).
I habe one, that works as a PCMCI as well as PCI (You insert the PCMCI card in a slot in to convert it to PCI)

But: No DHCP so far...
Manual setup in 30 seconds.

I've tested about five other card 'till a friend found this one in one of his drawers.
I'm quite exited
