You can stop suffering from the NIH syndrome, and use the current
approach in Liberté (choosing the kexec'ed kernel type according to
the CPU type + memtest), or use the old memwipe approach (sequential
chain of processes with each one clearing a reasonable amount of RAM).
I normally ignore endless discussions about trivial issues on this
mailing list, but I just can't watch someone who for once apparently
actually knows programming waste his time on such a useless endeavor.
In the end, you will go back to kernel-based approach, because too
many users will have issues with something custom like GRUB / MemTest
modules, which may have issues with obscure hardware, not see the same
memory that the kernel sees, will not be portable to non-x86 /
non-BIOS architectures, etc.
