This graphic chip doesn't have a DRM driver and fall back to vesa-framebuffer driver. Without this patch, users of such chip suddenly see their GUI broken without any indication or reason of what happened (no error message). Hence this regression is near to impossible to troubleshoot for end users. Such case was reported https://bugzilla.opensuse.org/show_bug.cgi?id=1187154. Rather than adding another exception in the udev rules to deal with such HWs, they instead get their own hwdb file '60-seat.hwdb'.
