2mb cache works, with cm based roms, because they redirect /cache to /data if /cache is under 20mb - maybe it still does with this, as there's a bit of overhead for the filesystem, so it's just wasting 18mb in that case. /cache is only used for market downloads & a few small log files in clockworkmod, nothing else.
If /cache doesn't get redirected to /data, sd-ext or tmpfs, then the size of /cache dictates the maximum size app or game that you can download from the market.
Maybe something like 180mb system / 2mb cache would be better, or 200mb system if we must. Standard European blades only have about 210mb system, 220mb is just for the Chinese stock roms, so rom devs need to keep it under 205mb including all addons. I'll wait & see.
