Edimax Card Initialisation fails (I/O space problems?)

I have an Edimax EW-7105c+ PCMCIA Card which I
believe uses the Texas Instruments ACX100 chip. I
have followed the instructions closely but get a
failure to install even though Mandrake 9.2 running
Kernel 2.4.22-21 and using the Network Connection
Wizard recognises the card correctly. Running
start_net as root gives the same result. Can you
shed some light on this. The following is from
dmesg. The card has been correctly inserted and the
card manager has been activated and updated. I am
using pre4.

Thanks,

acx100: It looks like you were coaxed into buying a
wireless network card
acx100: that uses the mysterious ACX100 chip from
Texas Instruments.
acx100: You should better have bought e.g. a PRISM(R)
chipset based card,
acx100: since that would mean REAL vendor Linux
support.
acx100: Given this info, it's plain evident that this
driver is EXPERIMENTAL,
acx100: thus your mileage may vary. Visit
http://acx100.sf.net for support.
