Ok, I haven't see that via is different from the removed midi code from 
intel ac 97, because it is only for VT82C686 and the midi port is on the 
pci device.
Anyway, we should check if the midi device is found by pnp for these 
chips. If it is the case, what happen if mpu401 module is load before 
the via module ?

ns558 work even if the PnP is disable : it will try to see if there is 
something on the following ports [1]. And 0x200 is the port harcoded in 
the via driver, so it should detect it. But perhaps VIA_FUNC_ENABLE_GAME 
will be missing...

Thanks,
