I could easily imagine just adding a IORESOURCE_RAM flag (or SYSMEM or
whatever). That sounds sane. I agree that comparing the string is
ugly.

It's pretty much always been there.  It is indeed meant for things

yadda yadda. Just showing the numbers is usually useless for figuring
out exactly *what* something conflicts with.
