allocating memory during kernel startup

Hello,

I recently ran into this problem - there is no easy way to determine  
wether it is safe to call kmem_alloc() yet ( as in, are we far enough  
through startup ) and when we call it too early the whole thing just  
hangs.
Any chance to just have kmem_alloc() immediately return NULL if it  
isn't ready yet so we can fail gracefully instead of hanging?

have fun
Michael
