The man page (http://ftp://ftp.alaska.edu/pub/sois/man/drop_caches.html) indicates that "drop_caches" was only included in Linux Kernel V. 2.6.16 and later. DSL uses Kernel V. 2.4.31.

I don't know if there is another command used in earlier Kernels, but I doubt it.

DSL-N uses a 2.6 kernel (I can't remember if it was above 2.6.16, I think so), that could be another option depending on your circumstances.
