Yes, if the underlying packet capture mechanism and libpcap/WinPcap 
supply that information in a form Wireshark knows about (Prism header, 
AVS header, or radiotap header).

OSes: sufficiently recent versions of Linux, FreeBSD, NetBSD, OpenBSD, 
or DragonFlyBSD.  *NOT* Windows.

Drivers: most of the drivers for the BSDs listed on the Wiki page should 
support it in sufficiently recent versions of the OS.  The Cisco Aironet 
drivers on the BSDs don't.  I don't know what all of the Linux drivers 
do, but I think the Aironet drivers don't and the Atheros and Prism 
drivers do.
