It looks very similar to the approach that AMD took for AMD64; the
underlying architecture for the Intel's 64-bit extensions looks like
netburst architecture (Pentium 4). According to the manual the
sample-based performance monitoring hardware should work the same as
before. There are some changes in the PEBS stuff because the registers

Personally, since we have hammer in the names already, ia32e seems
