Grub on Etch amd64 works just fine.

Len Sorensen knows a lot about running amd64.  Consider that before you
write off what he says as FUD.

Etch it doesn't exist and can't be backported.  So flash in Etch needs
the ia-32 chroot.  I don't know if anything else does since I don't use

May or may not work, depending on the code and what all libs it needs.
