I just tried the pd6729 driver in FC2-test (2.6.5 kernel) with same
prosedure. No success.

With 2.4.20-19.9 and pcmcia_cs 3.1.31 it works. See below.

Anybody working with this driver?

I think there might be people who will soon notice that their PD6729
based hardware is not working any more after they are updated to new
linux distro coming with 2.6.x kernel.
