what is the difference? why should one be prefered over the other?
is peer somehow bad or are you looking to test biosirq? fwiw i'll try
out biosirq when i get the chance and see how it goes.
besides grovelling through linux/arch/i386/kernel pci code is there
some documentation on this subject?
the only thing i could dredge up was your kernel list posting from
october (thanks deja news!) in which you wrote:
