One of our major priority for next release is to get a variety of
hardware validated. Between SM-BIOS, ACPI and default values, I think
we will be able to cover a majority of them.  I would give ACPI more
priority than PCI probing. 

ACPI approach:
"dev_acpi" project gives user-space device access to ACPI name space.

Anand,

   Very cool!  I'm glad you've found it useful.  Please let me know if
you find any bugs or have suggestions for the interface.  I have a
handful of minor changes (including basic support for 2.4 kernels) so
I'll probably release a new version of dev_acpi as soon as I get some
time.  It's exciting and encouraging to hear of projects like yours
making use of it.  May I reference your project as a consumer of
dev_acpi as I continue to try to get it into upstream kernels?  Thanks,

        Alex
