Architecture: x86_64
Machine: amd64
>Description:
I just wanted to try the XFree86 vesa(4) driver on my amd64 workstation,
and noticed that the server failed to launch claiming that it cannot find the
module:

(**) VESA(0): Using "Shadow Framebuffer"
(II) Loading sub module "shadow"
(II) LoadModule: "shadow"
(WW) Warning, couldn't open module shadow
(II) UnloadModule: "shadow"
(EE) VESA: Failed to load module "shadow" (module does not exist, 0)

This module is not currently built with src/x11 framework (but present if
made using xsrc).

For a temporary workaround, just set the "ShadowFB" option to "Off", and
the X server with the vesa driver will work.

Some other drivers may fail too (fbdev, neomagic, trident), but the
"ShadowFB" option is off by default.

>How-To-Repeat:
Start XFree86 server (built from src/x11) with vesa(4) driver.
>Fix:
I successfully built and installed the `libshadow.a' module on my
amd64 workstation with the following sets of patches.
But other platforms must have their xserver list updated too (i386, ...).
