Yes , if you use kernel 2.2.x , you need to remap your physical free
memory.
exemple :
typedef struct
{
int data1[56] ;
int data2[89] ;
char videobuffer[1024*768] ;
} TMap ;
TMap *mapping ;
mapping = (TMap *)ioremap(PHYSICAL_FREE_MEM_BASE,FREE_MEM_SIZE) ;
and then , use the virtual address pointer mapping structure ...
