Ok, here is the first report: If I remove the statement:

     include port 0x100-0x4ff

from my /etc/pcmcia/config.opts file, then my NE2000 compatible Ethernet
Adapter does not work anymore. BTW: you said 'include io=0x...',
shouldn't that read 'include port 0x...? Anyway, here are the errors I
get when I remove the statement above: 

Oct  8 20:45:46 blackbox cardmgr[124]: initializing socket 1
Oct  8 20:45:46 blackbox cardmgr[124]: socket 1: RPTI EP401 Ethernet
Oct  8 20:45:47 blackbox cardmgr[124]: executing: 'insmod
/lib/modules/2.2.12/net/8390.o'
Oct  8 20:45:47 blackbox cardmgr[124]: executing: 'insmod
/lib/modules/2.2.12/pcmcia/pcnet_cs.o'

Oct  8 20:45:47 blackbox cardmgr[124]: get dev info on socket 1 failed:
Operation not supported by device

In a functional system (when the include line above is not removed) I/O
ports in the range in question _are_ used by PCMCIA functions:

(5)root@blackbox>cat /proc/ioports 
0000-001f : dma1
0020-003f : pic1
