Last DRM warning (typed over from a photo). Note the tainted flags(!)

Since a few cycles, it seems that nouveau is preventing the kernel from
correctly displaying OOPS, BUGS and Warnings etc etc.

This is because the DRM system seems to provide warnings each time the kernel
kills X and moves to console to display these messages.

Today, I enabled some debug options and captured the last WARNING by this
system. NOTE: The oops is typed over from a camera photo, so it might not be
entirely accurate.

This is an 32bit UP system with the notorious(?) Geforce FX5200 (NV34). I
attached the Warning as an attachment.

I modified rsyslog to log directly to disk, hoping to capture more information.
When that happens, I will post more.

I think this is also a regression, usually I got errors about page faults and
stuff.
