Description of problem:
The attached patch simply adds an identifier for the upcoming zx2 ia64 chipset. This is necessary for support identification purposes and to enable the changes in X which look for the identifier. There is no functional change the the iommu code.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot zx2 system
Actual Results: System works, but chipset is identified as Unknown. This looks bad and causes X not to loaded the chipset driver.
Expected Results: chipset identified as zx2

patch to add izx2 identifier
Patch first present in 2.6.9-6.38.EL. Would be good to get testing from HP,
which probably means getting them access to the kernel :-) Moving to MODIFIED.
Has HP confirmed this fix?
not to the best of my knoweldge yet.
verified on 2.6.9-6.46.EL
