KDE-based Distro for Testing Accessibility

Hello, everyone.

I was just wondering if there is a distro available which I could 
specifically use for the purpose of testing KDE accessibility with Orca 
as well as KWin's magnification capabilities. Right now I am still using 
Ubuntu 11.10, and I am still in limbo as to which distro to settle down in.

But as I mentioned, I would like to find a vanilla KDE distro which I 
could use to test KDE with Orca, qt-at-spi, Zoom, and so forth. From 
what I heard on yesterday's episode of the Linux Action Show, it seems 
like Arch would be a great base, but I have no idea what I would need to 
install to get accessibility up and running.

I really want to see KDE flourish as a great desktop option for myself 
as for other disabled users. As a blind user, I am excited to see the 
strides taken to make KDE usable with Orca.

Any suggestions would be greatly appreciate.

Thanks for your input.

Kind regards,

Bob
