It is really unsupported
PCMCIA driver development
Problems with TI PCI1031 PCMCIA-Controller (Armand Portmann)
Date: 2000, Jan 27
From: David Hinds <firstname.lastname@example.org>
(that seems obvious, since the drivers don't recognize it and the documentation doesn't list it as supported)
However, I would have expected that it would work anyway. What card(s) have you tried to use, and what were the results?
No other cards tested by Armand Portmann, 2000, Jan 28
Have you tried any cards at all? by David Hinds, 2000, Jan 28
