I was running the AHCI driver on the freebsd-current tinderbox for 3 
weeks with very good results.  I had to recently change back to the 
ata code as smartmontools are not (yet) supported and one of the 
drives started to throw errors. Other than that, I found it to be the 
same speed or faster (depending on the workload). This was on a 
Phenom 9950 Processor and ATI IXP700/800 SATA300 chipset on AMD64, 8G of RAM.
