*LOL* it doesnt make anything into portraitmode, so no, it will never be in CSSU. -Cssu is just a big joke, and completely useless ... unless you think portraitmode is important.
However, i havent tried batterypatch and i dont really have any use for it either, but i do like what speedpatch do for *me* and also would like it on my main linux-mint installation because it also has the same problems as my N900 did have before speedpatch.
