Select graphics card for console output

I have an HP DL380G9 server with two discreet nvidia graphics card installed running RHEL 6 with Kernel 2.6.32-573. Both cards have the same chipset (NV117) but different models. K620 (Slot 5 address 88:00.0), K2200 (Slot 4 address 84:00.0). The K2200 is the selected card for Linux to output plymouth and boot messages. Swapping the cards results in the HP Server BIOS hitting a page fault, even after clearing CMOS and BIOS settings. Swapping the cards back fixes the issue. There is no option in the BIOS to select a primary discreet graphics card. Linux appears to select the graphics card with the lowest PCI Bus Address. Is there a kernel command line option or some other configuration file to select a different graphics card for the default pre-X11 display?
