The s3c24xx support is still in the I-pipe patch, if it was not, the
compilation of the kernel with CONFIG_IPIPE would not even work.

This port has been contributed a long time ago. Since then, we use an
"optimistic testing strategy", we make sure that the port compiles, but
 we assume people really having that board are in charge of testing our
releases. Not having a board based on this chip, it would be hard for us
to test it. IOW, I have no idea whether it is supposed to work.

I suggest you assume nothing, read:

And try and debug your port. It even contains a tip for the particular
case you are mentioning.
