So I finally got around to trying this out on my Linksys WRT54G (version 8.0) and the flash was successful. The documentation for the process wasn't as clear as I would have liked but I read it over a few times before attempting it and it seemed to be enough to get me through it.
I ran a before and after benchmark on SpeedTest and even though the new firmware is faster, its by such a small margin that I'm sure if I ran it several more times the average would be about the same. Still the main reason I tried it out was to see if it would be more stable with the PS3 over WiFi, and also in the future if I get a new router I'll be able to use this one as a wireless bridge. I won't know for a while if the stability is better now but hopefully it is, because with the original firmware it wasn't *that* bad really and usually I don't mess with things like this that are already working fine.

So has anyone else tried this yet and what are your thoughts? I was originally going to flash to the Tomato firmware, which I heard good things about, but after getting into the documentation I saw that my version of the router wasn't supported.
