Update, Problem solved and the solution was quite interesting. The BIOS of an E6400 enables you to set the behaviour of the SATA-controller, the options are ATA, AHCI and IRRT (Intel Rapid Recovery Technology). It was set to ATA in order to enable installation of Windows XP which apparently doesn't play nice with IRRT and AHCI (blue screen on boot anyone?). FreeBSD works just fine for the AHCI and IRRT options but choosing ATA will give you an IRQ storm.
