PS1: 
This should probably be a new patch set in cb:73097. However, all of this also applies to the B75 Pro3-M, which is already in coreboot, so fixes would be welcome there as well.

For the B75M-ITX, I'd add these to cb:73097. For the B75 Pro3-M, it's definitely worth uploading a separate fix for this.

Regarding the change itself: TESTED working on B75M-ITX. However, this should probably be part of cb:73097 for this board. For the B75 Pro3-M, however, you should upload a separate patch, as that board suffers from the same problem requiring the same fix.
