You could also go with mobile shell and get down under 40% use on boot. I had my TP2 down to 38% in use on boot with the nopush/SSK, MobileShell3.5, oggsync, launchmanager and fingermenu all running on bootup@. 133.44 MB free
Imagio:
~78% stock TF3D w/ showcase taskmanager
~64% removed TV, nopush (not needed on imagio)
, SSK TP2 Dynamic Resource Proxy.cab
~52% ResProxy "ShareMemSize" 0000000 and OggSync 84.55MB free 95MB in use
boots a little slower with resProxy at 0, no problem.
