testing Ubuntu on ARMv5...does that mean there will be an ARMv5 Ubuntu "release"? You didn't actually say, and I'm not going to assume "testing" means "release". It could mean a PPA for all I know. If there is going to be an ARMv5 release... just throw out another press release.. or and addendum...or an announcement on a mailinglist anywhere that can be referenced for n810 owners who aspire to run Ubuntu.
Failing that is there going to be something for ARMv5/ARMv6 like the non-supported community powerpc/sparc ports already open inside Ubuntu?
