into a loadable module, and all of the platform dependencies are gone (except for the alpha_XXX_dmamap() thing, which is another issue -- I still don't know how to use the busdma stuff with a network driver). Also increase the delay in xl_reset(); testing on a 486/66 with a 3c905C shows that reading the EEPROM fails immediately after a reset. Waiting a little longer after the reset completes seems to fix it.
