Hi Dave,

One way to hack it so it never starts is just to rename the bootanimation executable in /system/bin.

I just tried it and my Android boots in a reported 2m or so, about 5 minutes of real time. You get a line like this in the boot output but there are no apparent ill-effects.

[ 14.863680] init: cannot find '/system/bin/bootanimation', disabling 'bootanim'
