Stock kernel 2.4.0 and pcmcia package as provided in rawhide falis to initialize some cards on my notebook. Mainly my ethernet card 3C..575... which was driven by 3c575_cb in the old package and worked fine. If I use the kernel pcmcia it just doesn't even detect the card (it does fine on my modem card in the next slot!)...Only way I could get it to work was to exclude pcmcia support from the kernel, and build the pcmcia package with CONFIG_PCMCIA=n so that it build all the drivers....this still does not work with the current pcmcia-cs package since this has different config file that assigns 3c575 to 3c59x driver...so going back to pcmcia-cs package from 2.2.16 kernel did the job.
