I would also see pdaxng sometime... I'd like to kexec pdaxng and cacko.
I predict that SDHC cards will be the only SD cards one can purchase in the very near future.
I have tried Angstrom and dual boot with cacko, but Angstrom isn't exactly for me.
I'm more of a GUI guy, I forget commands if I don't use them often.
Edit
I decided to "stick with" Angstrom for awhile, there's some really basic things missing or difficult to figure out, but it's a learning experience.
