        OS/Version: Linux (All)
            Status: NEW

Afer an upgrade to xorg-server-1.7.0.902 and latest git for the kernel and 
xorg nouveau drivers I cannot start x with kms under wmaker. As root (just twm 
and an xterm) it's ok.

Dmesg shows:

and the display is powered off. At this point I need to ssh to the machine as 
reboot it.

If I don't use kms, I can start wmaker just fine:
