Sure it does.

In fact, in sufficiently old versions of the vesa driver, it does dpms
by banging on the VGA registers directly, which is a rather stunning
failure since VBE defines a DPMS call that stands a chance of, you know,
working right.  Newer versions of the driver (although not yet any
released version) use the VBE DPMS method instead.
