Hi.

I've now had this EQ overflowing notice with a 1920x1200 display on the =
GeForce 7800 GT.

I'll note that I've updated to ports r368074 which updated Xorg, the =
drivers, and even gcc (to 4.8.3). This was on...

FreeBSD FBSDG4S0 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r271215: Sat =
Sep  6 23:56:15 PDT 2014     root@FBSDG4S0:/usr/obj/usr/src/sys/GENERIC  =
powerpc

but booted on a G5 PowerMac quad-core (so lots of unused RAM for =
powerpc/GENERIC).

Context:

I built a 10.1-PRERELEASE r271215 (to test Justin Hibbits' changes for =
powerpc). I also used portsnap and then rebuilt my ports from scratch.

(I'd be surprised if this was powerpc or PowerMac specific. But use of =
these old cards may be more likely for PCI-Express PowerMacs.)
