the Belkin F5D6020 wireless card is supported.
But there are at least 2 different chipsets available
with this card. I have a Belkin F5D6020 version 3
(according to lspci, 0000:03:00.0 Ethernet controller:
Belkin Wireless PCMCIA Card - F5D6020 (rev 20)). This
has a Realtek 8010 chipset which is not supported by
orinoco_cs or, AFAICT, any other pcmcia-cs driver. I
suspect the original supported version is not widely
available any more.
Please note this incompatibility in the SUPPORTED.CARDS
file, to avoid other unsuspecting users wasting time
and money on this card. Thanks very much!
