Maemo 5 has kernel versio 2.6.x.
And Debian versions 4-6 had kernel versions 2.6.x.
But what i386 Debian version I should use, I remember that some of these version (was it Debian 5?) come with new bug that never fixed not even today Debian versions:
https://bugs.debian.org/cgi-bin/bugr...bug=464962#143
That prevents run it with Cyrix, Via, Transmeta and Connectix i586 CPUs. And ofcourse I want test with those

But what else needing, I think those Debian versions installation DVDs does not have Hildon-desktop as option, am I right?

EDIT: But it seems that it have been in testing version short time:
https://tracker.debian.org/pkg/hildon-desktop
Is that testing version impossible to find these days?
