I've tried various setting in the OS configure and messed around with ndiswrapper just to see if I might be able to get it to start post boot.
First of all, which distro or flavour of Unix are you using? If you're using Linux, make sure your kernel is 2.6.11.4 or later. If you're not using Linux, it will probably be a lot easier if you switch to Linux.
I found this article for using ndiswrapper to configure the WPC54G Linksys PCMCIA card on Linux: http://www.t3i.nl/myblog/?p=31
Hope this helps
