Yes, but you'll have to buy Sniffer Wireless or AiroPeek (which supply
their own drivers, which can put the card into monitor mode, unlike the
drives that come with Windows or with the wireless card, which don't
support that - those are the drivers that WinPcap-based applications
such as Ethereal use).

Some Linux drivers (and some BSD drivers) for various wireless cards, unlike
the standard Windows drivers for those cards, support monitor mode.

If by "the FAQ" you mean the Ethereal FAQ, it also says
Q 5.36: How can I capture raw 802.11 packets, including non-data
(management, beacon) packets?
A: That would require that your 802.11 interface run in the mode
called "monitor mode" or "RFMON mode". Not all operating
systems support that and, even on operating systems that do
support it, not all drivers, and thus not all cards, support it.
so it also depends on the OS, as well as the driver and the card.
