There are two sets of problems with that The first is that quite a few machines crap themselves if you do this because nobody has ever tested things like the IRQ routing or the firmware on suspend/resume when they find the hardwared controller has gone for a walk. Putting it back on suspend might help in some cases but then you get to pick your way through the documentation minefield, deal with device changes while in non AHCI mode, figure out how to set up registers the BIOS didn't etc. Would be a good project for someone with a lot of patience anyway as the AHCI mode is also 64bit capable and *much* faster overall as it doesn't keep stalling the CPU poking imaginary registers and turning them into messages on the SATA bus.
