Xorg log file after trying to rotate screen

Tested on Lubuntu 12.04 i386 , compiled OpenChrome from git.

Current setup: Wyse Vx0LE
http://www.parkytowers.me.uk/thin/wyse/vx0/WyseV90LE.shtml , 
lspci shows: [S3 Unichrome Pro] (rev 01), 
HP LP2065 4:3 monitor, VGA mode (DVI-VGA adapter) 1600x1200 60hz. 

I installed ARandR and tried to rotate the screen and/or change resolutions. If
I go 180' a dialog box comes up and says:
XRandR failed:XRandR returned error code 1: xrandr: Configure crtc 0 failed
See pic: https://flic.kr/p/DrMXB9

If I rotate 90' or 270' the display blanks out and the login box appears after
a bit. (X crashes).

If I try to change resolutions the display blanks out and the login box appears
after a bit. (X crashes).

dmesg shows:
agpgart-via 0000:00:00:0: AGP V3 bridge
agpgart-via 0000:00:00:0: putting agp V3 device into 8x mode
pci 0000:01:00:0: putting agp V3 device into 8x mode
