No problem.

Umm, if this is the stock INSTALL kernel from 4.0.1 distribution,
0x0e0bf7d6 is in fpu_implode() function in
sys/arch/m68k/fpe/fpu_implode.c.

Does your 3/60 actually have 68881? I.e. what does dmesg say?
FPU should be reported right after Model like this:
---
NetBSD 4.99.59 (GENERIC3X) #53: Sun Apr 13 06:12:29 JST 2008
        tsutsui@mirage:/usr/src/sys/arch/sun3/compile/GENERIC3X
Model: sun3x 80
fpu: mc68882
total memory = 65536 KB
avail memory = 62224 KB
 :
----

I'm not sure if FPE functions could be called even if
the machine has a real FPU, though.

INSTALL kernel doesn't have ddb(4), so "trace" output on the ddb
prompt after panic with GENERIC kernel might help.
(see ddb(4) man page for details)
