Presario R3000 con Broadcom BCM4303

Ciao a tutti,
ho appena installato Lucid su un Compaq Presario R3000 che monta una wifi Broadcom

lspci | grep Wireless

Codice: Seleziona tutto

02:02.0 Network controller: Broadcom Corporation BCM4303 802.11b Wireless LAN Controller (rev 02)
A fine installazione, dopo aver messo gli aggiornamenti per la lingua, è spuntata fuori l'icona dei driver proprietari con il b43legacy che ho installato correttamente ed attivato.
Ora però all'avvio, il LED della wireless fa un piccolo cenno e poi rimane spento.
dmesg | grep b43 da questo risultato:

Sembra perciò che il pulsante hardware disabiliti la scheda, cosa confermata anche da rfkill list che restituisce:

Codice: Seleziona tutto

0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
ma anche dopo aver dato sudo rfkill unblock all non è cambiato nulla.

Per completezza riporto anche il risultato di lshw -C network:
