Hello,

There seems to be a difference in how Xorg server can use direct
rendering depending when radeonkms.ko was loaded: at boot time vs. at
a later time (but not necessarily at X startup time). The difference
is that direct rendering could not be enabled for X in the former
case. In the latter case, direct rendering was successfully enabled.

I'm semding Xorg.log.0 of the session with direct rendering failed to
set up, as well as dmesg covering the two last sessions: one with no
direct rendering (radeonkms_load="YES" in loader.conf) and the last
one with direct rendering (radeonkms was loaded at X startup time, not
system boot time).

Please note that there was a LOR (kmslk, drmslk) at boot time of the
"first" session with radeonkms_load="YES" in loader.conf
