+	  Typically on m68k systems the kernel will not start at the base
+	  of RAM, but usually some small offset from it. Define the start
+	  address of the kernel here. The most common setup will have the
+	  processor vectors at the base of RAM and then the start of the
+	  kernel. On some platforms some RAM is reserved for boot loaders
+	  and the kernel starts after that. The 0x400 default was based on
+	  a system with the RAM based at address 0, and leaving enough room
+	  for the theoretical maximum number of 256 vectors.
