maemo.org - Talk - Using "ps" to get nice value of a process

Recently, I've been trying to decrease the lag of my new bluetooth keyboard, and someone suggested that I could do this by reniceing the existing bluetooth processes. I've tried to do this, and now I'd like to confirm that the change was made. Normally, I would just use on of the options of "ps" or "top" to display the "nice" value of the process, but the busybox version of "ps" doesn't support this. Does anyone know of a way to get this info? More generally, is there a place that I could download the "full" versions of these programs? I downloaded bash already, and I did find a website with GNU "ls", but no "ps" so far. Thanks for any advice.
