Ok I got that reproduced. (And described.)
This looks very much like a Kconfig bug (which Sam Ravnborg
already knows of) I think. See:
CONFIG_PCMCIA_PCNET depends on CONFIG_NET_PCMCIA
CONFIG_NET_PCMCIA depends on CONFIG_PCMCIA
CONFIG_PCMCIA *depends* on CONFIG_PCCARD
CONFIG_PCMCIA *selects* CONFIG_CRC32
and here, IIRC, is/was the bug, that a config option which has both
depends and selects does not correctly work. CONFIG_PCMCIA_PCNET
should inherit the state of CONFIG_PCMCIA, that is, if PCMCIA
("16-bit PCMCIA support") is M, the pcnet_cs driver automatically
becomes M too (if the bug was not there).
