But, AFAIK, NEW_XORG does not break VESA, so making NEW_XORG default regresses nothing. I am running with KMS and have no access to vtys once I start X. I can see no regression from "It's broken" to "It's broken". And VESA is pretty broken on it, though I lived with it for about 9 months until the first release of KMS for testing on 9. Is it the case that NEW_XORG breaks syscons on some pre-Sandybridge systems that would work with UMS but won't work with NEW_XORG? If that is the case, I do understand. I was not aware of this issue.
