Pretty close the latest code is not in 2.4.19.  There should
be more in 2.4.21.  It is a challenge getting a kernel with drivers
for the latest hardware.

On the opteron, fun.  The answer is that the map drivers handles that part.
But you will probably need the latest from the mtd cvs tree.

The modules I think you want are:
mtdchar
amd76x
jedec_probe
cfi_cmdset_2

I'm a little fuzzy as I usually build everything but the map drivers
into the kernel.  Basically you don't want the map driver loaded when
you hot swap chips as that confuses it, because it doesn't have the
concept of hot-plug.
