What driver, I assume fbdev? What framebuffer device?

What depth? The fbdev driver used to set the colormap to blank the screen at
least in depth 8, it could be that your framebuffer device doesn't fully
support that.

That could be DPMS kicking in?

This is a bit more than my average dose of speculation... :)

The XFree86 4.1.0 has much better blanking and DPMS support so I'd be curious
how that would do.
