1. There a was a typo in one place where the processor family is
checked (16 vs 0x16). Now the checks are consolidated in a single
function.
2. Instead of an array of struct amd_et_state objects the code allocated
an array of pointers. That was no problem on amd64 where the sizes
are the same, but could be a problem on i386.
