Would I maybe be better off reinstalling the whole shebang and have the wifi-card inserted from start in order for the centos installer to see it properly from the beginning?
before you do that, open a terminal, become root, and run /usr/sbin/kudzu (while the wireless card is installed). that's the program that does hardware detection; it may be able to sort out your issue.

or if kudzu for some reason doesn't cooperate (which is always on my system) become root run : /sbin/modprobe prism54 run : dmesg | tail and read whether it just says it has loaded the module (single line) or detected will output a wlanX statement and you are in business
Isn't it implied that since "prism54" is listed in /etc/sysconfig/hwconf for the wifi-card that the module has been loaded already? Or is this some of the magical stuff that sometimes doesn't happen for whatever reason? 8-)
/etc/sysconfig/hwconf is the file kudzu creates when of all detected hardware at startup and it related this hardware with drivers in the kernel but certain drivers are modules in the kernel, wich need to be loaded manually or later when the system is already running this can be done by method 1 explained here above or adding them in /etc/modprobe.conf which makes it load the modules at startup you will need to add the line (if it is not yet there) : alias wlan0 prism54 you can check whether the module is loaded with : /sbin/lsmod | grep prism54
Excellent explanation. Thx.
