yes except that PB KDE still requires maemo... so you'll need to clone diablo or chinook to whatever partition you are going to use for PB KDE.

By "Deblet and KDE4" i assume you mean Deblet WITH KDEv4 ..

Then yes.. 3 partition on MMC1; 1 swap, 1 Diablo with PB KDE; 1 Deblet with KDE4

All MMC2 with Easy Debian on it.

In all honesty though.. I wouldn't do that. If you want to boot to debian - just use deblet.. don't use 'easy debian'. You can setup qole's sripts to use Deblet to integrate into the Maemo environment.. So you would have

MMC1 with Swap and Diablo with PB KDE
MMC2 with Deblet and Gnome, Icewm, and KDE4.

There really is no point for a whole debian just for a KDE since PB KDE gives you KDE3 in Maemo... that also allows you more room for both maemo and debian for apps and anything you do while booted into debian will carry over to your maemo debian (since they are the same debian)..

did that make sense?
