If you aren't dependend on microb (which wasn't operable anyhow when I had that problem), you might wanna set a chmod -x on the browserd executable. But some hildon-whatever will constantly try to execute browserd, which is no longer possible...so it creates some kind of fake load. It won't slow down your device, but it looks horrible in conky Had the problem even after a reflash, now waiting for the nokia download page (for emmc image) which seems down for two days now
