I am wondering about this also. It is stated right on the Yellow Dog PS3 page the following:
"*With YDL v5.0, the PS3 is fully supported with the exception of the NVIDIA graphics card (see note on Graphics). "
Fully supported includes wireless, since that is one of the main selling points of the 60GB model.
So even though it does not use it by default, it should still be able to.
If anyone from Yellow Dog could get back to us on the driver we need to use to get Wireless working that would be great. Even someone else on the forums who might figure out how to get it working.
It is a Marvell Chipset, 88W8580-BAN1.
HAHAHAhahahahahahahahaha.
