Subject:   Latest update to ATI driver broke in same way as using DRM-next did

So this is kind of interesting - I posted here last month about trying to
use drm-next and it not finding my 2nd monitor properly. I did try and
subscribe to x11@ but for some reaosn that didnt work, and I didnt worry
abotu it too much so didnt investigate further as I wont be running 12.0
for a while.

But this morning I just did a small update of ports, and it upgraded the
driver from xf86-video-ati-7.9.0_3,1 to 18.1.0,1  ... and that acts
in the same way, i.e. only runs on one monitor and cant see the 2nd.
I thought it was a bit too much of a co-incidence, as I would guess both
the old and new drivers share substantial amounts of code.

I rolled back to the old driver and this is the dmesg outoput
it gives if thats of any help...
