Subject: hwinfo problem since 2.6.28

Since 2.6.28 my hwinfo tool crashes badly on 2 years old OpenSuSE 10.2
x64/SMP.
Older kernels run fine, I did a "make oldconfig" and rather used
defaults (just skipping low-64k checks).
This seems to be the only affected binary as far I can see.
Did I miss a new legacy/compat option or is it a bug?

Thank you!
Daniel
