You may try the following ISO CDROM image with the standard vmware image found in the Download section of Zeroshell webpage.
Just replace within the vmware configuration to point to the new CDROM image.
Upon booting the default is to run kernel 220.127.116.11. However the old 18.104.22.168 is also present and can be activated at boot prompt pushing option 1 or 2 (verbose).
I have added ath9k and ath5k on top of the other madwifi stuff and also the VIA padlock. Note that within vmware it is of no use, I know!
For the time being, my advise is not to try dumping this onto your CF card as I have not tried myself and am not sure about the size of the ISO. Once I tried, I will submit the procedure in order not to crash your system and remotely.
