I've just tried this, and indeed: Setting Threaded Optimization from
Auto to Off yields the "good" result.
So maybe we should try to reproduce this with pure OpenGL and send a
sample to NVidia (they have been very responsive in the past if you send
an example)

Dear Wojtek et al.,
This mail reminded me of an issue I had a couple of years ago with VBO's on a
particular Windows pc with a 9800GX2. I thought it was an issue of that PC, as
it was quite unstable, so I didn't report the problem at that time. The
solution I accidently found back then was to turn off Threaded Optimization in
the NVidia Control Panel (Auto per default).
But now I'm getting the bad result of your test on a GTX 480 (266.58 driver), and that
"fix" works again. After turning off Threaded Optimization, I see the proper
gradient displayed.
Could you try this as well?
Kind regards,
Ruben

minute please let me know how the test passed on your machine ;-)
tested on two more for you, both Debian 32-bit.
1:
dual nvidia GTS250s, driver 270.41.19, good result across 4 screens.
2:
nvidia 9600GT, driver 280.13, good result on single screen.
