-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.
-

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.
