Um... If you havn't checked out the PnP patches, you should. The whole
point of his work is to make a SINGLE consolidated resource management format.
You request_hw_resource() and give it flags of what type of resource, and what
range. It is far superior to the current method (which is what you just
complained about... a different interface for each kind of resource, and many
different resource allocations between different archetecures.)

Plug and Play is a really BAD name for it... it's better described as the
Linux resource management project. PnP is just one part of it.

ObTechnicalquestion: has anyone played with the semantics of supporting
memory holes? And how to get that information from bios?

I checked the patchlist and didn't see anything of the type.
