Who has a FirePro V5800??

Hi!

I'm trying to turn a HD5770 into a FirePro V5800
There is the softmodded way with hacked drivers but this work with outdated drivers and don't seem to produce real gain
I've tried to modify the bios by changing device ID and it doesn't work too.

So finally i've decided to flash my card with a V5800 bios to test if it works
I can't find anywhere a FirePro V5800 bios to test.....

So is there someone here with this graphics card? and can you rip your bios to test it
(I've got 2X HD5770 in Crossfire so i can burn one without problem as i don't play games anymore on this machine :p )

Thanks in advance
