Everything compiled just fine, with the 2.4.23-pre9 kernel, but when I 
plug in my WG511-card, I get the
following message in /var/log/messages:
    Nov  1 16:46:41 laptop pci.agent[974]: missing kernel or user mode 
driver prism54
If I do a "lsmod", I can see that the prism54 module has been loaded.
