no fundamental objection to the x86 bits.

shouldnt this:

+       if (!in_interrupt())
+               return 0;

just be eliminated and the cr0/TS save/restore be made unconditional?  
irq-assymetric APIs are not nice in general.

Reading/setting cr0 isnt _that_ slow. (or if it is, by how much does it 
slow things down, exactly?)
