Anyone have Tyan S2880 (Dual Opteron) and got the onboard broadcom adapters working?

I've tried the tg3 module, I've downloaded the bcm5700 module from Tyans 
site and tried it too.  Neither of them detect the dual onboard GigE 
adapters. I've made sure the adapters are enabled in the BIOS, I've 
tried booting with acpi=off, etc...I even removed all the PCI cards from 
the machine to ensure there are no conflicts. I'm running out of ideas, 
does anyone have this board and gotten the broadcom adapters working?  
If anyone has any suggestions I would be glad to consider them as well.
