$ setpci -s a.0 0xc9.b

will display the value of this register under Linux, and:

$ setpci -s a.0 0xc9.b=value

will set it to the desired value. However, check that a.0 is the
cardbus bridge first by using:

$ lspci

The correct solution is to put a quirk into the kernels yenta driver,
but we'd need the results from your testing first.
