Let me comment on a few things:

You normally want to replace this with just

    Load "extmod"

as DGA is deactivated otherwise. This is from an outdated example XF86Config,
way back somewhere at 3.9.x when DGA wasn't working yet.

These ViewPort and Virtual values are default for the specified mode and as
such not needed.

There is no depth 32 in X 4. 32 bpp is depth 24, fbbpp 32. If you want 32 bpp,
add

    DefaultFbBpp 32

under the DefaultDepth line and

	FbBpp		32

in a Display Subsection for Depth 24. OTOH maybe it's the default anyway
(driver dependent), grep -i bpp /var/log/XFree86.0.log tells for sure.
