Its not. Until someone can explain why the original cast pointer as pointer
to volatile fix I tried didnt work I have to assume that gcc 2.8 has
broken volatile handling. I will never support a kernel built with a compiler
with any known volatile handling bug. Its _far_ too critical to the net code
that volatile and the __asm__ behaviour work as documented.
