When I upgraded my A3000 to an '040 (3640), I found that the FPU version
of Caligari 24 no longer works.  Apparently, it wants to see a real '881
or '882, not the FPU on the '040.  I can run the Integer version, but it
is horribly slow.  For example, a simple animation that took 2 hours, 40
minutes on my machine with an '030 and the FPU version of Caligari 24 took
2 hours and 20 minutes with the '040 and the integer version of Caligari.
Needless to say, a mere 13% speed improvement is a little disappointing
for an upgrade that supposedly (according to SysInfo) quadrupled the speed
of my system.  I know some of that rendering time is dependent on disk
access speeds to save frames, etc., but still..

When I try to start the FPU version, the machine simply locks up.  BTW,
the same is true of Scenery Animator 4.0, except that it gurus the machine.

Is this normal?  Is there any way around it, to get it to use the FPU
versions of these programs?

Also, SysInfo does report for FPU, "68040+68882", so the machine knows it's
there.
