You don't need to load another module, since __wake_up_sync is part of the kernel. You are probably running into a problem with module versions. When you do:
$ grep __wake_up_sync /proc/ksyms
you will probably get something like:
c01147e0 __wake_up_sync_R08c2a6b5
The _R08c2a6b5 part of the symbol name is the version, which comes from the ".ver" files in your kernel include tree. You will have to include <linux/modversions.h> to get the correct definition for __wake_up_sync.
By the way, 2.4.7 is an extremely old kernel, and you may avoid problems by moving to something newer.
