Having spent an ungodly obscene amount of time trying to get two 
different USB audio cards to work in 64 bit opensuse, I suggest not 
trying to be a pioneer. I solved my need for multiple sound cards 
(exceeding the number of PCI slots I have) by using a PCI bridge.

For one soundcard, you can try thing:
http://www.siig.com/ViewProduct.aspx?pn=JJ-000111-S1
It doesn't list linux in support unfortunately. However, the latest 
linux kernal might recognize the card. Then pick a soundcard from the 
list of supported devices.

For my particular situation, I bought a Magma PCI expander on ebay. I 
plugged it in and it worked with the soundcards I had on hand (Diamond 
5.1 using C-Media chipset). With the shipping, it worked out to be about 
$39 a PCI slot. [My time, about 10 minutes, not counting searching 
ebay.] Thus the price for the SIIG seems reasonable if you only need to 
run one card. However, I can't vouch it will work. The Magma boxes do 
work, but are obscenely expensive new and bulky.
