la questione dei driver in linux è differente e in realtà molto + semplice:
a me è successo lo stesso (che fedora non mi vedesse la scheda)
io farei così:
apri un terminale: come root (se non sei root basta che scrivi "su" e tichiede la password)
[root@pcmatteo ~]# service pcmcia status :questo ti dice se il driver PCMCIA è attivo:
[root@pcmatteo ~]# kudzu -p :taderà un po e poi ti da una lista di tutte le periferiche collegate al pc
tu devi trovare la tua scheda nella lista e scriverti il "vendor id" e il "product id"
ora dovresti sapere quale è il modulo adatto alla tua scheda, per esempio quello per la mia
che è una asus WL-100 è "orinoco_cs". così con queste informazioni ho installato la scheda come segue;
[root@pcmatteo ~]# vi /etc/pcmcia/config : vi è un editor di testo, ma puoi aprire il file /etc/pcmcia/config
con qualsiasi editor preferici, sempre come root!
io ho aggiunto questa voce (3 righe)
card "ASUS WL-100 fichetta Wireless"
manfid 0x02aa, 0x0002 ;questi due numeri sono rispettivamente il "vendor id" e il "product id"
bind "orinoco_cs"
con questo ho associato il modulo a la mia scheda e facendo
[root@pcmatteo ~]# service pcmcia restart
la mia scheda ha cominciato a lampeggiare, quindi il kernel la vedeva.
ora do un occhiata se trovo la tua scheda, sono su messenger.

dev.raid.speed_limit_min = 10000
[root@pic042 etc]# sysctl -w dev.raid.speed_limit_max=100000
dev.raid.speed_limit_max = 100000
Se pone en el fichero /etc/sysctl.conf y la velocidad ha mejorado:

The final part is to install the gmetad portion of ganglia somewhere with a web server. The LCFG server is one very good option for this.
Follow the ganglia instructions to set up gmetad.
It is also a good idea to add the central GridPP Ganglia as a trusted host to your gmetad configuration.
To do that your /etc/gmetad.conf file must contain at least
trusted_hosts 127.0.0.1 130.88.200.150 130.88.200.151 130.88.200.152\
130.88.200.153 194.36.3.0/24
which is some hosts at Manchester Computing Center. Finally send Andrew McNab the hostname of gmetad server so he can monitor it.
