Devfs is concerned with loading device drivers when a device file is 
accessed, it shouldn't cause IRQ conflicts or errors, it probably will 
produce warnings that modules cannot be loaded because the underlying 
h/w device doesn't exist but that's all.  Also devfs is not selectable 
in kernels later than 2.6.12, it's being removed shortly.

I'd say it was unlikely, what version of kernel are you running?  If 
it's the latest (i.e. 2.6.13) then you'd be best to email the alsa devel 
list if you can't get your sound card working, OSS likely to become 
deprecated in the near future... (plus ALSA is a whole lot better!)

Thanks
Mark
