There are wireless units that supports both 5.8 and 2.4 at the same time those are the dual-band units, i.e. http://www.linksys.com/products/group.asp?grid=33&scid=35
As Larry said, mixed mode is used if u have both G and B units in use on the same AP, the reason that G mode will not support B units, is that B units do not understand the OFDM modulation used by G (to boost performance to 54 Mbit/s). B uses CKK and Barker code. But in mixed mode the chipset uses different modulation for each session, this is not very well implemented so if you have G and B units on the same AP, the G units will take a big performance hit because of the switching between OFDM and CKK.
