I assume that your Linux system uses the hotplug scripts to initialize 
PCI, usb and other modern bus devices. Thus the hotplug scripts react to 
the kernel detecting components and mostly the kernel reports the 
Mainboard chipset features first. If you want to change the order of 
your soundcards you have to tweak your hotplug system. I would suggest 
you try the following.

Add those devices which correspond to your two soundcards to 
/etc/hotplug/blacklist. Note that your real soundcard drivers should 
suffice here (like snd_sb*, no need to put the generic ones like snd_pcm 
in here). If you reboot your system you can check with "lsmod" that no 
soundcard specific drivers have been loaded.
Next you can load those manually in your boot script, I would suggest 
you add them to /etc/init.d/rc.local (this could be slightly different 
depending on your linux distri). Here you load the soundcards drivers 
with "modprobe" in your desired order.
