Shouldn't this be fixed in the kernel, then? What exactly does it actually 
fix?

40 minutes on any kind of 2GHz system would probably mean at least 2 hours for 
me... I'd recommend at least having a local USE flag or variable to enable/

If a version compatible with both kernels could exist, perhaps asking in some 
related IRC channels could find someone interested in writing such?
