Thanks for your quick reply, thorazine74.

I did as you said and went without NVInject, AppleATIATA and AppleSMBIOS. SMBIOSEnabler and SMBIOSEFI are not in this release. I suppose I have to mod my own install DVD to include those kexts, right?

Anyway, all went almost the same way, this time the monitor went off right after the initial grey Apple screen, no blue/grey screen or mouse cursor this time. Also, what should I look for in the -v report so as to identify the offending driver/kext?

I'm willing to try the 10.5.4 option as a last resort. I have the Ducky release ready to be burned unless further tweaking with the iDeneb release solves the problem.
