The solution is understood better in the mac's inability to boot primarily off of any desired medium through default unless it is specified within the boot options. The solution would be an attempt to get the mac to boot off the harddrive in the event that its boot priorities have been screwed up (resulting in the white screen of death).

In gist, it basically boots perfectly into the mac os (sounds and all.

Based on your initial query, I think its of value to note that there are two categories of problem regarding white screens on macbooks.
