Cool, I'm glad that worked out for you.  Just as a note, checking for a
file in proc will probably only work if your system loads the modules
for you automatically when you plug in your removable card.  If you have
compiled the alsa module for your external card into your kernel, or if
the module must be loaded by hand, a different approach may be necessary.
(something like greping the output of lspci to check if your card is there.)
