I'm not sure the problem that this person ran into is related to the drive 
being a SSD.  I'm under the impression that enabling AHCI after you've 
already installed the operating system can lead to problems.  A quick search 
pulled up this MS article on correcting a stop error that can occur if you 
do this with Vista or Win7, for example. 
http://support.microsoft.com/kb/922976  Apparently, the problem described in 
the MS article has to do with the these operating systems disabling drivers 
that are not being used, in order to speed up the boot time.  A driver will 
need to be manually re-enabled, before changing the BIOS setting to AHCI 
enabled.  (I believe this problem can be avoided by enabling AHCI before you 
install the OS (and supplying the needed driver using the F6 method, if the 
OS doesn't have what is needed).)

I didn't go back to the Tom's forum to make sure this applies in that 
person's case, but I thought this information might be of general interest.

I'd feel negligent if I did not say what happened on the other list.
The guy turned on AHCI in his BIOS and the box would
no longer boot.
He had an Image from this morning, so all is fixed.
I'm not sure what happened.
(Watch out...)
Right before that, I had warned him there were problems in Nov 2009.
