You can also add other IO ports to /etc/pcmcia/config.opts (where
include port 0x4000-0x4fff already seems to be present), e.g.

include port 0x100-0x3af
include port 0x3e0-0x4ff
include port 0x820-0x8ff
include port 0xc00-0xcf7

The parent PCI bridge doesn't need to be adjusted as long as it is
"transparent", which is most often the case on notebooks and x86 desktop
systems.
