Intel Pro 82546 chipset performance

Is there a PPC compatible driver available for this the 82546 Intel Pro
1000. I was just handed an SBE lanPMC card with this chipset on it
yesterday. I am trying to use it on an 8265 based system with a 2.4.21
kernel. The driver in this kernel crashes on startup. A quick look at the
driver makes me think that it has never been used on anything but x86. Am I
misreading the situation? Is there an enhanced driver available?
