Ok. I just posted to the NEWS group suggested in the documentation of
the IBM JVM. Let's see if anything comes from it.

It is just a plain 750CXe 600MHz. I guess those were used on the ibooks
before the 750Fx. That said, i suppose there may be trouble with the
subarch detection. My box is a Pegasos, and it says :
processor : 0
cpu : 745/755
temperature : 31-33 C (uncalibrated)
clock : 601MHz
revision : 51.17 (pvr 0008 3311)
bogomips : 1199.30
machine : CHRP Pegasos
Maybe the JVM has trouble with the Pegasos attached to the machine type, or
the 745/755 cpu id, which could be more precise maybe.
Mmm, i wonder if the temperature reading has any meaning in this case.
