Firstly you should not be compiling the kernel with gcc 2.96, you should be using kgcc. Search recent l-k archives for kgcc.
Secondly that is a warning that section .modinfo was initially created without the allocation bit but later usage of the section implies that the allocation bit should be set. Creating .modinfo as non-allocated was an old kludge to stop the module descriptive data being loaded into memory as part of the module. modutils 2.3.19 onwards force .modinfo to be non-allocated (and hence not loaded into kernel memory), even if the allocate bit is set. Feel free to try this patch, it is not urgent so I have not sent it to Linus "code freeze" Torvalds yet.
Against 2.4.0-test11-pre6, it might fit 2.4.0-test11.
