What's the hsync fudge factor used for?

I noticed that the left edged of my screen moved a bit when I was 
switching between 32/16/8 bpp modes and tracked it down to this.
The same thing here - both with Radeon VE QY and 8500LE (don't remember
the exact chip version).  Adding the opposite value to the fbset
parameters puts the image back into the place - so it looks like the hsync
fudge is unneeded at least with these chipsets.

Probably this fudge factor was needed for some early chips?
