Ok man sounds great! Well, actually your hackie which I used to boot with does give full rez at 1280x800 but it defaulted me back to 800x600 or something on reboot after I installed the voodoo_dmg file (not one of yours).

I have just tried the external display (an Asus 22 inch from my other pc). All visible again till the load screen and same white image. I will now try to take a screenie of whats going on for you. Cheers
