So, you have 2 video outputs:

One is R128:
> [    32.185] (WW) R128(0): DDC2/I2C is not properly initialized
> [    32.185] (WW) R128(0): DDC2/I2C is not properly initialized
> [    32.185] (II) R128(0): EDID for output VGA-0

It doesn't see any monitor.

Another is modeset (kernel) based driver for i965 (built-in video card)
>[    33.240] (II) modeset(G0): [DRI2]   DRI driver: i965
> [   33.240] (II) modeset(G0): [DRI2]   VDPAU driver: i965

There is a monitor there
> [    33.005] (II) modeset(G0): EDID for output VGA-1-1
> [    33.005] (II) modeset(G0): Manufacturer: DEL  Model: a00b  Serial#:
860631884
> [    33.005] (II) modeset(G0): Year: 2004  Week: 41

Just a random idea: disable (via BIOS setup) built-in card and disconnect
monitor from it
