Bill is correct; the FPE problem with the LC040 is (at least partially)
solved only in -current kernels.  I am not 100% convinced that there is
not still a problem, however, due to the way the FPE handles effective
address calculations for its operands (in an 881/882/030-specific

I am having a similar problem with PowerBook 500-series video, which I
hope to resolve before I give the machine back to its owner this week.
