You can get the absolute mostest newestest (sorry, I'm getting redundant...my bad) builds of zImage (yes, no extension) and modules here (http://glemsom.users.anapnea.net/and...htc-msm-linux/). I'm using one from 8/29 or 8/30. You can simply swap them out at will, obviously outside of android. Just keep them in a separate directory. I have 2 or 3 on the sd card just in case (don't know in case of what, buuuut...).

Hope that helps.
