Does anyone know whether multi-mode wireless PC cards such as the D-Link DWL-AG650 which run 802.11a, b, g will work in a G4-1 ghz Titanium? If so, in OS X or OS 9.2.2, and at the higher (a, g) or lower speeds (b)? These are not supported by the manufacturer on Macs but may run in the Mac OS like other 3rd party (802.11b) cards.
