Hi,

the current device probing code for mace,bmac and gmac returns always 0
and the module can be loaded even if the required hardware is not
present.

Hint: insmod errors can be caused by incorrect module parameters,

Can we change that behaviour?
de4x5 and pcnet32 return -EIO as example and the module is not loaded.

The attached patches fix that problem.
