This can lead to ring-buffer overruns resulting in

16bit Compex cards identify themselves as being 8bit.
While these cards will
work in 8bit mode, much higher performance can be achieved by specifying
.Cd "flags 0x04"
(force 16bit mode) in your kernel config file.
In addition, you should also specify
.Cd "iosiz 16384"
to take advantage of the extra 8K of shared memory that 16bit mode provides.

The Mitsubishi B8895 PC Card uses a DP83902, but its ASIC part is
undocumented.
Neither the NE2000 nor the WD83x0 drivers work with this card.

The D-LINK DE-650 has funky resources that differ from other cards and could
likely be made to work.
Its shared memory interface conflicts with other resources on many
laptops and cannot be moved.
The pccard(4) layer does not support activating a CFE that it fails to
allocate all the resources for.
