Measures against coold boot attack

there is th idea of a panic button that whipes the whole ram. how long would that take?
is there a command/feature/bug that lets the ram module whipe its memory without having to access each address?
if whiping takes too long would it be better to have a laptop run with unscrewed ram cover and in an emergency rip out the module(s) and break them?

how long would that take?
Not too long. RAM is fast.
is there a command/feature/bug that lets the ram module whipe its memory without having to access each address?
Not that I know.
if whiping takes too long would it be better to have a laptop run with unscrewed ram cover and in an emergency rip out the module(s) and break them?
Probably not.

This is something that host operating systems such as Debian and Fedora would have to implement. Someone could take http://git.tails.boum.org/wiperam/, polish, and upload to Debian.
