Thanks taharka, but it didn't work. I did it as you said, except I also
copied the newer modprobe.conf to modprobe.conf.was and then after it
didn't work I compared the two. No difference.
There is, however, considerable difference between the lsmods from the two
installations. In fact, there is so much difference I am amazed. just a
short sample of the two lsmods.
Lsmod from 1376 kernel

lsmod from 667 kernel
