I personally never had a system with several videocards enabled
simultaneously, but perhaps the uncertainty in the order they are enumerated
by the kernel could be solved in a similar manner as for other types of
devices. Here are several recipes I used elsewhere.

1) /etc/modprobe.d/usb-controller.conf

This ensures loading the ehci USB driver before uhci and ohci:

softdep uhci-hcd pre: ehci-hcd
softdep ohci-hcd pre: ehci-hcd

2) a rule in /etc/udev/rules.d which defines the enumeration order of two
different audio devices (one was RTL HDAudio chip on the motherboard, the
other HDMI output on the ATI graphic card):

SUBSYSTEM!="sound", GOTO="my_usb_audio_end"
ACTION!="add", GOTO="my_usb_audio_end"

DEVPATH=="/devices/pci0000:00/0000:00:03.0/sound/card?", ATTR{index}=1
DEVPATH=="/devices/pci0000:00/0000:00:1b.0/sound/card?", ATTR{index}=0

LABEL="my_usb_audio_end"

3) another method in /etc/modprobe.d which corrects enumeration of two audio
devices, both controlled by the same snd_hda_intel driver (one is HDAudio on
motherboard, the other HDMI output of the on-chip Intel graphics):

# Reverse HDA Intel cards ordering:
options snd_hda_intel index="1,0"
