Linux has suported multiple soundcards in all it's distros for years.
The most usual way is by adressing them 
as /dev/dsp /dev/dsp1 /dev/dsp2 etc but you can also adress the 
induvidual parts of the soundcards directly in the latests distros 
as /dev/snd/C0D0d where the number after C is the card, and the 
number after D is the DAC/ADC and the last d or c is output or 
capture.

My current linux ham system is running with 3 soundcards without 
problems.

Most onboard soundsystems are AC97 chipsets, these do most of the 
work in software and that might be part of the reason it's turned 
off when you plug in a soundcard.
