Does it actually have a memory in it when you try this?

When the device is totally misidentified like this (whic it is), it's a 
sure sign
that the cardbus code is totally confused.  If I recall, this happens 
when the
memory and I/O window registers in the cardbus controller have not been set
up right.  I suspect that no cardbus cards work for you.  The cardbus 
code has
issues that have not been resolved.
