how so?  The libpfm4 event names are more or less the same as that from 
the manuals with the exception that . is replaced with : in some cases.

Which vendors provide "original tables"?  None as far as I know, you are 
stuck digging through PDFs.

Unless you mean the tables that come with Vtune... are those licensed in a 
way that is useful?

libpfm4 also provides at least minimal event descriptions along with each 
event, will the kernel/perf provide those too?
