If you read the Start Manager on Inside Mac Vol. V, they state among
other things, that the order of events follows as:

   - the video card is searched, and initialized.
   .
   .
   - resource manager initialized.
   - StartUpScreen looked for, if found display it.
   - Apply ROM Patches.
   .
   .
   - Determine System Heap from info on System Folder.
     (SUS accounted for, here?).
   .
   .
   - Load INITs.
   .
   .

This looks to me as if no ROM patches will solve the bug, and changing
the boot blocks won't either (I guess).  Looks like a very deep ROM
bug (unexpurgable by software).  Although, a kludge after the facts
may solve the problem (a CLEVER kludge).
