To the best of my knowledge, there is no way to get an ICH6 into AHCI 
mode if the BIOS has set it up in legacy mode. I wrote some code that 
basically does what lt_hotswap does for SATA devices that worked fine on 
my ICH6 test machine (a Dell rather than a Thinkpad, but shouldn't 
matter in this case), but it needs much more polish before it's 
integratable.
