Ed: Can you elaborate on the reason(s) for your methodology:
"We routinely load base registers and "uninitialized" pointers to 7FFFF000 (or sometimes 7FFFFBAD) rather than zero." The one reason I can visualize is that instead of unintentionally accessing something in low core you would experience a S0C4 instead. Thank you.
