Arm variations
The ARM processor has several variations.
When Ubuntu supported ARM they built armv5el
When Debian supported ARM they built armv4t ( eabi armv4 + thumb)
(cf building for i386 or i486 ... i486 code won't run on old 386 CPUs)
The armv5el code makes better use of newer hardware and runs faster on it so the main Mer support is for Ubuntu. We have a Debian port to support the slightly older devices (and to keep options open)
The Nokia internet tablets are armv6 The Freerunner is armv4
Future Ubuntu releases (Karmic) will be v6+ and maybe, eventually higher.
