>Description:
I had some existing hardware (1U intel sr1300 servers) that I was trying to add
sound cards to.  Unfortunately, I am limited to sound cards that have the 3.3V pci notch in them otherwise I would just use different soundcards.  I have verified the cards work fine if they are loaded as modules with a non-PAE kernel.

PAE kernels with "device sound" and "device snd_emu10k1" will


>How-To-Repeat:

Take the stock PAE config file and add the "sound" and "snd_emu10k1" devices:

# diff PAE PAE_emu10k1    
23a24,26
> device                sound
> device                snd_emu10k1
> 
#



config PAE_emu10k1
cd /sys/i386/compile/PAE_emu10k1
make cleandepend && make depend && make
