Pinyin with hardware keyboard support needed

[Koterpillar]

I want to be able to input Simplified Chinese - but I don't want an entirely Chinese OS. After some searching I've found these (I'm not sure if I remember the names correctly):
CE-Star - doesn't work well at all. For me, at least.
"Ask China_FEPNo5" - mysterious thing, but it does let me input everything using stylus. No predictive input. (EDIT: I think the credit goes to asukal)
PlumSIP No. 5 - takes a lot of space on the screen, but no hardware keyboard support.

There should be something built-in in the Chinese ROMs, and a lot of cooks starting with Dopod ROMs must have stripped it down - so can anyone give me an idea of where to search?

Thank you. This forum required a registration to view, and I found a discussion of yet another ROM build. However, download links simply do not work.

What I hoped for would be some information about where is the IME itself stored in ROM... now I can only compare that and the stock one, but there are too many differences, I'm afraid.
