I just tested your 1.8.0 version announced in distrowatch
as it is a live cd, I tried to use it with virtualbox as I did with 1.7.2 release, but for this one, at boot time, Austrumi tells me 'unable to boot, this kernel requires a feature not present in your cpu : pae
I know that my virtualbox installation (version 1.6.6) supports pae (I'm using it on a Pentium mobile 1.7Ghz), and a friend tested to boot it on another virtualbox installation (version 2.4.4) and it's the same. he also tried to boot it directly on his computer, and error is the same...
maybe a bug on this version???
