Not sure if it is related, but there is a 30+ second delay in the X startup at this point:

Any ideas as to what's going on here?
To follow up on my own message, I have traced the problem down to the xf86DoEDID_DDC2 function in X11, which lives in hw/xfree86/ddc/xf86DDC.c in the xorg source tree.
If I disable DDC2 in my xorg.conf file like this:
Section "Device" ... Option "NoDDC2" ... EndSection
the delay is gone.
So - is this a driver issue, or a LinuxBIOS issue?
Thanks, Ward.
