Comparing boot messages from booting with "good" and "bad" versions of
BootX, I saw that the amount of RAM is OK in both cases, but then I
found one quite incredible thing, and this is essentially the only
difference in the boot messages. Booting with BootX version <= 1.1.3 and
any kernel, I get as usual

   kernel: Calibrating delay loop... 133.12 BogoMIPS 

Booting with BootX-1.2b2, I get with the same kernels

   kernel: Calibrating delay loop... 11.39 BogoMIPS

This is repeatable, but for me quite incomprehensible.
