Virtual machines?
Something to consider perhaps is the use of lguest, which is currently i386 only, but does boot up nearly instantaneously, and can be scripted, as its console is the launching shell.
Is there an efficient technique for mounting a disk image so that changes made to it are discarded?
Sure, just create an LVM writable snapshot of your master image, and boot with that instead, and throw away the snapshot when you're done.
