I must admit I have not kept up with PS3 Linux since it got restored and we saw all the hacks a couple of years back. Hopefully you are on firmware 3.55 or earlier.
I would say something about the browser but trying to use the ps3 browser is painful and suggesting you try something on it would be cruel.
WINE will not do anything here, you will need a full virtualised machine to use windows which is not good on the PS3 (though if you want to restrict yourself to DOS you might get somewhere).
On an android phone... the question did come up the other day http://www.romhacking.net/forum/index.php/topic,20974.0.html
Short answer there is you could do something you already knew about but I would hate to work up.
You do not need a fancy PC for ROM hacking, give or take some of the really crazy emulation and searching programs which you do not need to use for 99% of ROM hacking, so I would instead suggest picking up a cheap XP or refurb laptop. People seem to be giving them away these days.
