Sorry. I think I must explain: I'm using linuxbios on this Geode system, so 
there is no SMM emulation of the sound hardware. Thats why I'm searching for 
a solution to forward the SMI to a regular IRQ. Has someone experience in 
programming this SMM code? Maybe a short routine that only triggers a regular 
interrupt when an SMI occures would help.
