I am having problems loading the nvram driver, nvram.o.

This was compiled on a Linux (FC4) box, and has an md5sum of 
031a3c521b089919e5fd7ded72e8f7a1.

I have two ts7250, one with 32MB flash, the other with 128MB, and a ts7260.

Although I used the ts7250_config option, this module works on the 7260 but 
causes both 
7250 to hang.  By hang, I mean the insmod command never returns and the box 
must be 
power cycled.

After recovering from the hang, the md5sum of the nvram.o file has changed 
although its 
timestamp has not.  The 'new' md5sum is always be642970caa05a07444b934389343880.

On the ts7260, the md5sum of nvram.o stays as it was.

So the questions are:

Should I expect this module to load even though the kernel that is running had 
# CONFIG_NVRAM is not set
in the .config file, which I had changed to 
CONFIG_NVRAM=m

Build process:
make ts_7250_config
(edit .config as mentioned above)
make oldconfig
make modules

What is the difference in the kernel between 7250 and 7260 that would account 
for this?

The output of uname -a is identical on all three boxes:

Linux ts7200 2.4.26-ts11 #22 Tue Jun 6 12:23:09 MST 2006 armv4l unknown

Grateful for and ideas.

Martin
