rv516 x1300 1002:7183 is discrete desktop PCIe card.

Before apt-get full-upgrade on Bookworm today it was last upgraded in early May,
then running 5.18 kernel and mesa 21.3.8, and both 1920x1200 on DVI and 1680x1050
on VGA worked as expected. Now with 5.19 or 5.18 kernel and 22.2.0 mesa, both
displays fail to sync if the modesetting DIX is used.
<https://paste.debian.net/1255583/> is Xorg.0.log. I recognize nothing in it that
would explain the sync failure.

All is good using the radeon DDX.

openSUSE Tumbleweed's 5.19.10 & 5.19.8 & 22.2.0 echo the Bookworm behavior.
