    In anycase, it looks like GCC just breaks when you use the

Actually this is a bug in the code using va_arg. There is even a 
flag for GCC to catch implicit int promotions for variadic functions,
because the variadic function has to use int.
And the flag is on, the compiler does warn about this. One more reason 
to get
our kernel -Werror ready :)
maybe we should feed warnings of at least kernel compiles to a 
webpage/mailing list? i'm doing world builds twice a day anyways...
