[ACPI] vendor resource descriptors: HowTo?

[John K. <jp...@sg...>]

Hello,
  I've got a question concerning the vendor resource descriptor
code. 

Basically it is:
 
 What is the recommended way for one to process vendor defined
descriptors?

The code in arch/ia64/kernel/acpi-ext.c looks to be exactly
what I'd need (acpi_find_vendor_resource(), 
struct acpi_vendor_descriptor, etc). 

Should I create my own copy of this, or just modify
arch/ia64/kernel/Makefile to include acpi-ext.c in my build?
In which case, my only issue would be references to 
struct acpi_vendor_descriptor.

Back in Sept, there was some discussion about moving the
vendor resource code: 
http://sourceforge.net/mailarchive/message.php?msg_id=12995951

Best I can tell, this has not happened yet?
Are there still plans to do this? If so, when?

Thanks for any help,
John
