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.
