If you basic problem is getting wireless to work. I would recommend the following 2 alternate procedures.
edit your file /etc/modules.conf
add the following line :
alias eth0 ornico_pci
Now I understand that you do not have Ocrnico wireless card, however this driver which comes inbuilt(in mandrake 9.2 atleast) is known to work with most of the wireless cards. It worked on my HP Pavillion ze5385 running Mandrake 9.2. Give it a shot and let me know if it worked.
If you have windows drivers working fine for your WLAN card, you can make them work on Linux too. There is a wrapper available which makes Windows drivers work in Linux. This can be downloaded from http://ndiswrapper.sourceforge.net/
This needs atleast kernel(2.4.25 or 2.6.4)
