I was thinking that by the time userspace is ready, the memory that can be tested will be less.

I do not think you need to modify anything in kernel. Just use /dev/mem to test areas that kernel doesn't see, then kexec into place you already tested, and test the rest. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
