Good :)
Does the LCD tell you which frequencies it's running on? According to
your log XFree tried to use 60Hz / 64kHz with the PGX64

I think we need to figure out which frequencies the onboard ATI uses to
make the LCD happy. In you XFree log there will be a list of rejected
video modes, like this: (II) ATI(0): Not using default mode "2048x1536"
(insufficient memory for mode) (II) ATI(0): Not using default mode
"1024x768" (bad mode clock/interlace/doublescan) (II) ATI(0): Not using
default mode "2048x1536" (insufficient memory for mode) (II) ATI(0): Not
using default mode "1024x768" (bad mode clock/interlace/doublescan)

after that there will be a list of usable modes and something to
identify what it's using: (--) ATI(0): Virtual size is 1280x1024 (pitch
1280) (**) ATI(0): *Default mode "1280x1024": 108.0 MHz, 64.0 kHz, 60.0
Hz (II) ATI(0): Modeline "1280x1024"  108.00  1280 1328 1440 1688  1024
1025 1028 1066 +hsync +vsync

please check what the onboard chip is using.
Then it may be worth checking what the card does when you tell it to do
1280x1024 in 16bit. =20

You can tell the firmware which mode to use:
setenv output-device /path/to/device/ATY,something:r1280x1024x60

have fun
Michael
