My guess was that enabling the card in BIOS simply switches the power of the WLAN card on. But I really don't understand why it's not detected then with my vanilla kernel. My naive thought was that the kernel scans all possible PCI[e] slots a chipset offers and finds all cards there. Seems to be a bit more subtle... > no magic patches at all. Well, they've at least added atl2 support, otherwise you had no wired LAN either. > Of course there's no driver for the wlan, but that's a different > story ;) I replaced that unsupported Atheros 5007 card with an ipw3945, so I haven't got that problem.
