I've tried everything I could come up with but no luck...
I guess I'm gonna let it be and hope the new version of 2007HE will be released soon.

As to the monitor, I've installed two, one is "load-applet"(https://garage.maemo.org/projects/load-applet/) and the other is CPU-meter(http://inz.fi/maemo/cpu-meter/), they both used to worked fine on my 770 with OS2006 but when I upgraded to 2007HE, both refuse to show up ever since...
