This seems nastier. Apparently, the MachZ processor can either address 32-bit
memory or multiplex a 16-bit memory a-la 386SX. It happens that some memory
sticks are 16-bit and others are 32. Those with 32 are fine. The system I'm
working on has a 16-bit 8MB RAM stick in it, and the kernel seems none too
happy about it. I haven't figured out exactly what part of the kernel has a
hard time with this 16-bit stuff ... and I haven't ruled out the silicon as
having issues.

BTW, the system does pass memtest86 with zero errors ...

Actually, looking at the comments in init/main.c, it seems "auto" is passed
by LILO:
/* In case LILO is going to boot us with default command line,
  * it prepends "auto" before the whole cmdline which makes
  * the shell think it should execute a script with such name.
  * So we ignore all arguments entered _before_ init=... [MJ]
