Code:
08048000-0817d000 r-xp 00000000 fe:00 110100910                          /mnt/cobra/Spellen/cod2/cod2_lnxded

The first two lines represent the memory of cod2, the 1nd is already in libcod:

PHP Code:
mprotect((void *)0x08048000, 0x135000, PROT_READ | PROT_WRITE | PROT_EXEC); 
0x135000 is calculated by 0817d000 - 08048000.

Try to add this mprotect:
PHP Code:
mprotect((void *)0x08048000, 0x135000, PROT_READ | PROT_WRITE | PROT_EXEC);
mprotect((void *)0x0817d000, 0xC000, PROT_READ | PROT_WRITE | PROT_EXEC);
