If libpcap/WinPcap on your system handles it, Ethereal can handle it -
Ethereal doesn't impose a maximum size on Ethernet packets.  (It can't
handle 802.3+802.2 packets that are that large, but neither can 802.3 -
the length field in an 802.3 packet can't be larger than 1500, otherwise
it's interpreted as a type field, and that's part of the 802.3
specification, it's not an Ethereal quirk.)

I don't know whether libpcap/WinPcap, and the underlying OS mechanisms
it uses, can handle jumbo frames on any particular platforms; I would,
however, be somewhat surprised if there were any platform on which it
*can't* handle them.
