Oh, nice. The commit log was an entertaining reading!
I'll try to re-test it on some 486 as time permits later.

Now as the effect appeared to be still clearly algorythmic rather than 
some hidden timing/caching/pipelining mystery, it probably could be 
implemented in bochs so as emulated 486 also behaves the same way? For 
me it'd look quite usefull.

Thank you,
