This bug is 100% reproducible on 32-bit linux (not 64-bit) when using the most
recent nightly builds of firefox to view www.npr.org.

The firefox devs changed something on Sept 10 (2010) that tickles this bug in
nouveau.  (The same firefox build works normally with the 'nv' driver.)

To reproduce the problem, download the latest nightly build of ff here:
ftp://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-4.0b7pre.en-US.linux-i686.tar.bz2

Then visit www.npr.org, that's all.  Xorg will begin using all of the cpu,
making the machine unusably slow.

I see the same when using the linus.git kernel, too, so this is not a brand new
bug.

NV34 [GeForce FX 5200] rev 161 on an older single-core AMD k8 processor.
