It doesn't look like bootmenu uninstalls via Maemo Application Manager. I still get all the bootmenu messages after removing Mer and uninstalling the Mer install and Bootmenu via Application Manager. The boot status bar for Maemo is now gone as well. Looks like I'm reflashing if I want to get rid of everything. I have Ubuntu running on my notebook, but I'm still way too intimidated by Linux. I'll just do the complete reflash and restore my data.
