Thanks for taking the time to hunt this down. So the comment was not
specific enough and so I was led into the illusion that this junk is
safe to remove after testing all the apps listed there.

So it seems this workaround is needed for nv3x. I will send a follow up
patch to correct this.

Woah, nv3x really has some weird problems. My nv49 shows the
splashscreen just fine. Fortunately I get a nv35 myself in the near
future, so I can test this on my own.
