There used to be a trick on the D630 that could work around the black screen issue if you had the wrong DSDT, but I only used that as a beginner and with Snow Leopard + ModCD. Basically, the trick was to boot with an external display hooked to the laptop and on which you force display using Fn+F8 at startup. Upon boot completion and at activation of OS X desktop, the display would return to built-in LCD. Give that a go, you never know...
