say i allocate the data for "section" at 0x100, and it's original paddr was
0x4. say the symbol has a vaddr of 0x32 in the relocation entry, and in
real-life it's at say 0x200.

then, if i understand this, is should come up with:

address = 0x200 - 0x100;

or,

*(long *)0x100+0x32 += 0x200 - 0x100;

allright, so, this sounds like i can do this:

long *p = (long *)malloc;

*(long *)section+r->r_vaddr += p - section;

for symbol malloc.
