[Vol-users] coldboot - usb, iso or distro - using LiME

Hello all, First congrats on a great tool :) I'm looking for some iso/distro to be able to do some "coldboot" testing, and i was thinking on using LiME module. Does anyone have done anything related to this, like a really small kernel booting to usb, and dump the mem? What do you guys use to do memory dumps? (on "real" systems not vm's ?) Thanks
