Comment # 165 on bug 91880 from Thomas DEBESSE

Note that all joined dmesg reports a HAWAII 0x1002:0x67B1 PCI ID except mine
reporting a HAWAII 0x1002:0x67B0 PCI ID (I also checked the dmesg joined in
duplicates of this bug). So the subset seems to be well known.

In fact I haven't checked in a while if my GPU is still affected or not, I
remember some firmware could change things. I will recheck, if my GPU works on
auto, it means only 0x67B1 would be affected.
