Naw, don't do anything rash.
Well, boil me in oil and call me a hush puppy. 802.11g? That's excellent!
If you're not joshing, thanks for setting me straight. Spank IBM, Novell, and RedHat for their evil lies - maybe it's a PPC vs. x86 arch issue? Any chance you installed a driver on the side, and it wasn't bundled with the kernel?
FWIW, it's not my opinion, its what Torvalds, Morton, et. al., consider mainstream and release. That is, the kernel.org kernels are "mainstream" kernels, as opposed to Alan Cox's patched "AC kernels", and 2 dot even are release kernels.
Alternative kernels frequently have unique features, like hardware support or iptables integration. Hence, my caveat that support might not be out of the box.
