On a slightly different note. Is is possible to adjust this HWRPB
value? A friend of mine has a UDB with a dead battery, and it now
thinks it is a 500Mhz Alpha! I don't know if it is a result of
that counter or not, but it fails to drop to /bin/sh when I boot
it. It loads to the point where it should ask which shell, and
stalls. It does this with a 1.3.2, a snpshot, and a -current kernel.
Occasionally it remembers its a 166Mhz and will boot correctly.
