Ok guys… the newest WRT54G v5.0 does not run linux… and you can’t run linux on it. So if you plan on getting one, you’d better go pick one up now and hope you can find a v3.0 or older on the store shelves.
However, you can still pick up the WRT54GS units, which still run linux (for now)… which is probably the better one to own since it has twice the memory and flash available for hacking.
There is also a rumor of a WRT54GL coming out, where the L denotes Linux… which may solve the problem of getting them in the future – we’ll see.
