This particular method is extremely deprecated, and is architecture-dependent as well. It is possible to add a function call within the body of mem_init(), which resides, for the i86 platform, in the file arch/i386/mm/init.c. In the middle of this function, two functions for initializing SCSI and sound-driver memory are provided. Also, arch/i386/kernel/head.S provides another platform-dependent way to allocate memory. This is where initial memory management is set up.
If you understand these well enough to muck with them, you don't need my help. These are last resorts for memory allocation, and you need to know exactly what you need to do, and why the dynamic allocation strategies will not work for you, before considering these “hacks”.
