the trick to GParted is after you apply the new map and the drive has been "Moved/Changed" right click the appropriate partition and select "Mount" then run the installer, you get a new option mine was "/dev/sda3" select that and it goes. the swap partition is automatically utilized.by the installer, no need to mount anything else. grub loaded up fine for me at the end of the knoppix install. even picked up the old winxp i moved all the way to the back of the disk, lol.

my only beef so far is the clock thingie, got that fixed with ntpdate, and a little root vi editing.
