Ah, you were taliking abount the "/proc/mtrr" change...

It's a "yes, it still happens" anyway:

$ cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size= 2048MB, count=1: write-back
reg01: base=0x07e700000 ( 2023MB), size=    1MB, count=1: uncachable
reg02: base=0x07e800000 ( 2024MB), size=    8MB, count=1: uncachable
reg03: base=0x07f000000 ( 2032MB), size=   16MB, count=1: uncachable
reg04: base=0x080000000 ( 2048MB), size=  256MB, count=2: write-combining
                                                      ^^^
