With the 1456 BIOS 'lspci' of my Linux cd ( www.sysresccd.org ) showed the 260 but not the 8800.
After flashing the 1606 'lspci' shows both cards :-)

Edit: Windows XP now also found the 8800GT and installed the Nvidia driver for it.
What BIOS settings did you use? How did you configure onboard graphics, disabled? How did you configure GPU detection order, GFX0 first?
I have a similar situation and just can't get it to detect the second Nvidia card.
