Are you willing to test some upgrade procedure to modify your CF card and bring a new kernel along with a new CDROM Z iso in the second partition. Your configuration will remain (3rd partition).
I do not have your Wifi card, at least not that I know of, and hence could not try myself.
The procedure should work as the kernel is up running in my vmware image and the upgrade through a modified reboot as mentioned in http://www.zeroshell.net/eng/forum/viewtopic.php?t=1500 has proved to work on my ALIX conf.
All that would be required is a USB key to temporary hold the new data of the first and second CF card partition. Of course this assume that those have standard size, namely roughly 32MB for the boot partition and 150MB for the second.
