I tried repartitioning the drive with Gparted from the Ultimate boot cd.
The partitions are set up right, but still no go, the installer stops at detecting the swap partition.
I also tried installing on a different system, a Athlon 64 3000, socket 754 with 2 Gb ram and a Geforce 7600, also no luck
I am giving up for now, i installed Linux mint KDE without trouble.
I wonder if anyone succeeded at installing somehow, i have some experience with Linux, but this bug is a real show stopper for me.
