Of course, the ARMedslack distro is "armv3, little endian, old ABI", so Debian arch arm, not armel; that means it's not easily bootable on any recent version.

It does make me wonder how hard it could be to start from there on an armel version, but I don't have the time. Maybe over Fall or Christmas break I could try a little; if I were to make any headway, then it can be a package-a-week routine in spare time.
