Wow. I don't think the bootblocks touch any PROM-reserved areas of RAM.
What sort of machines are these problems happening on - I'll see if I
can reproduce it here.
The only thing that comes to mind is the location bootinfo structure -
it currently starts in the "dbgmon stack" area. Michael, can you try
compiling a /boot with either the "BOOTINFO_ADDR" on line 113 changed to
0x8001f400 or 0x80068000? The first address is the "Ultrix temporary
startup stack", whilst the second should be well below the second stage
