That still counts as compatibility, the only way to really solve it is to allow the speed to be dropped.
Back in the 80's you could buy PC's that had a turbo switch, if you turn it on then the cpu runs at normal speed or turn it off and it slows down (to as slow as 4.77mhz iirc).
You can fix the software and a lot of it has been fixed when using whdload.
Dell PCs had a "compatible" stetting in the BIOS that did the same thing but well into the pentium era.
