You should be using the most recent - 1.00.d.  But, that's unlikely to
be the real problem here.

Have you tried disabling the cache in your build?  For a quick debug
test you can just change the lines in auto-config.in that indicate
caches, rerun menuconfig on the kernel and do a clean build.

Do you really have 256MB of memory?

Any other differences (even minor) in the auto-config.in files?

What version of the compiler tools, kernel sources, uClinux-dist are you
using?  Recent CVS?
