You swap the cards over, make a backup of the BIOS from a good card (or download one from the web http://www.techpowerup.com/vgabios/) and copy the BIOS back to the other slot.
The card in 16x slot 0, closest to the CPU, is the master.
I bricked a 7950 the same way writing to both BIOS with a bad BIOS and the PC wouldn't post. I pulled it out, stuck a 7850 in slot 0 so the PC would boot, and the bricked 7950 in slot 1, then wrote a good BIOS downloaded from the web (http://www.techpowerup.com/vgabios/) back to slot 1. Make sure you don't write it to slot 0!

What brand, part number and rev are the cards?
Use atiwinflash to flash the bios in windows.
Now atiflash in dos doesn't detect the 2nd gpu and well yeah now what?
[/B]Pull the BIOS chip and reprogram it separately, then solder it back to the card.[/B]Not sure if serious ....
Buy replacements off ebay and sell those.
If atiflash doesnt detect it, you can try the solution provided in the link

Pull the BIOS chip and reprogram it separately, then solder it back to the card.
how?
Well, you have to find the bios chip on the card (it will most likely be a SO8 chip, though just google the part numbers and you will find an EEPROM). You should have two such chips on the card (most likely, as the BIOS is separate for each GPU).
You will the need to desolder the chip (which is not fun for SMD chips at all), there are some guides on how to do that without destroying the chip.
Then you will need to connect that chip to a programmer (in a pinch I guess a Raspberry Pi could be modified to work as a slow programmer, but ideally you would need an universal programmer (read the description to see if it supports your chip).
Then you need to erase the chip and write the proper BIOS to it (using the software provided with the programmer) and solder it back to the video card.
Yes, it's not fun at all, but if you manage to brick a device by writing the wrong firmware, this is what you need to do. While your card may have a JTAG and/or ISP, it may use some proprietary codes to do it and you won't know the pinout too. Though if someone has a way to use the ISP or JTAG port for your card, then you can use that to reprogram the chip.

So heres the deal, I sold 2 5970's on ebay and I need to ship them on Thursday and I got my 280x's today and well was messing around with different bios files and well, I ACCIDENTLY put 280x bios on the 2nd gpu of the 5970. Now atiflash in dos doesn't detect the 2nd gpu and well yeah now what?
