Alan,

I just start to have a look (very busy right now)

That is already done :)

And so I still have to add 
#if defined(CONFIG_SUPERIO)
#    define ide_get_legacy(x) superio_get_ide_irq()
#else
#    define ide_get_legacy(x) ... (still have to find what)
#endif

and so change in drivers/ide/pci/ns87415.c

    hwif->irq = ide_get_legacy();	/* legacy mode */

Well in fact I do not yet well understand (less experience :( ) how do you
foreseen to manage this stuff for other platform?

thanks in advance for your understand.

By the way, in drivers/char/serial.c, also related to 'superio', i noticed:

#ifdef CONFIG_SUPERIO
    superio_serial_init();
#endif

Here I don't see how could it be kept out of generic drivers. Any idea?

Joel
