It won't work. The 6729 needs some special register settings. The chip
is similar to 82365, but not completely compatible. I have a PCI
wireless card from Samsung that needs it too (wireless chip is
connected using a 6729). David Hinds' driver supports it, but it is
some special case code in there. Adding it to the in kernel pcmcia
would require some work and it may be cleaner to do it in a separate
driver.

Whee. Those are getting rare.

Anyway, it really looks like it's a _PCMCIA_ bridge, not a cardbus one, so
you can forget about the yenta module. Basically, "yenta" is for the newer
32-bit-capable Cardbus bridges (which do have an i82365 compatible legacy
mode), and i82365 is for the old legacy-_only_ 16-bit PCMCIA bridges.

It should be an i82365-compatible chip (they almost always are - it's
either yenta or i82365 in the normal case, and the others are for some
really odd-ball things or non-PC-compatibles).

It looks like you tried every single module _except_ for the i82365.

Give that one a whirl. Just "modprobe i82365"

2.6.0-test11, PCMCIA,, Cirrus CL 6729 bridge not working

[Jani Vaarala]

I've been trying to get my PCMCIA bridge to work with 2.6.0-test11, but 
without any luck sofar.
My bridge works perfectly with 2.4.X series kernels and pcmcia-cs-3.2.5 
kernel modules (i82365,
with module options: irq_mode=1 fast_pci=1). 

It is a PCI-to-PCMCIA bridge based on Cirrus Logic CL 6729 (rev 07). 

Is there a way to get it working under 2.6 series kernels ? (as pcmcia-cs is 
not going to be supported
for 2.6 series kernels).
