Right.  But should the fact that we use ACPI instead of PNPBIOS make
a difference to userland?  My intuition says "no."  Obviously there
might be new devices and new functionality with ACPI, so there might
be new files and knobs in sysfs, but if you don't care about those,
it'd be nice if all the old PNP stuff just worked.

I don't want to delay pushing Zhang's patches upstream.  I think
they are definitely a step in the right direction.
