Hmm, strange.  X didn't even try to load vesa from the looks of it.  I'm not 100% sure if it's even supposed to if there's and xorg.conf, I think perhaps not.

Does it autoload vesa if you get rid of it?

Also, any particular reason for disabling nouveau, should we have a bug for that too?
Comment 5 Tomas Pelka 2011-09-23 09:10:46 UTC 
Ohh crap I forgot on ol xorg.conf.

So you are right removing xorg.conf will fix this.

So I think NOTABUG, or?

BTW speaking about balcklisting, it acts same in moth cases (blacklist/not blacklist).
Comment 6 Ben Skeggs 2011-09-23 09:23:42 UTC 
Yep, if that fixes it it'd be find to close as NOTABUG.

Yeah, blacklisting isn't necessary with nomodeset.  Nouveau will load, but it won't actually touch the device at all.
