I have finally bought this Abocom FE-1500 (http://www.abocom.com/fe1500.htm). It works !!!
It is recognized as a NE2000 compatible ethernet card, and it works both at 10 and 100 mbits.
Here is an extract from my /var/log/messages :

I am running a 2.2.16 kernel with pcmcia-cs 3.1.8 (redhat 6.2).
I think you can add it to the list of supported fast-ethernet cards. And thank you very much for your great work !
