seems to be a good idea.

you're using pcmciautils...so you have to run pcmcia-socket-startup
to write the new values. also after boot, to make sure it's setup, do a:
	cat /sys/class/pcmcia_socket/pcmcia_socket0/available_resources_setup_done
and:
	cat /sys/class/pcmcia_socket/pcmcia_socket0/available_resources_io
to see the configured ranges

looks fine so far...
