I believe this is normal - right after reset you'll probably see the ISP 
bootloader at the bottom addresses of the flash. Another idea - do you 
have the bootloader-entry pin properly connected to proper voltage 
level? Maybe it's the ISP bootloader that's causing you trouble?

Good to know that the cable is so good (; It was the one with ferrite 
attached permanently, right? Currently these cables are not available 
and I have different ones (without the ferrite), hope they are as good 
as the previous ones (;
