The registry edits and changing bios is what is supposed to make those drivers load. Microsoft's drivers (MSAHCI) will do well. I ran my SSD with them for about a year and was very happy with it. If I understand the problem correctly, it appears the problem is in your bios. The issue seems to be you setting AHCI in bios and bios not saving the settings. The honest answer is I really don't know. Bios should save whatever settings you change if you save and exit after making them.
Just to clarify, I did trick the BIOS into saving AHCI setting. But then Windows wouldn't start. Can anyone suggest next steps?

Well you can try starting in safe mode and /maybe/ you'll get lucky and windows can install the proper AHCI drivers, then reboot in normal mode. I've actually gotten this to work.

Otherwise there is a longer approach but you need to start with it back working again and make some changes to the registry. There is a tutorial here:

change storage controller to AHCI mode post install (win7 64-Ultimate)

I would check with Lenovo and see if there's a BIOS update. It appears to me that's where the problem starts. It could be that the chipset doesn't support AHCI or SSDs. Keep in mind this is a Core 2-Duo from 2008. I'm not familiar with Lenovo notebooks but I find it odd that PCI is one of the interface options for disk. Perhaps the chipset for the host controller is combined with the PCI bus controller and the BIOS doesn't implement AHCI. It wouldn't be the first time a manufacturer had stepped firmware (options) to control price levels among model groups.

Just a thought.

In earlier posts there was considerable discussion regarding "over provisioning" and SSD size/capacity with particular focus on Intel SSD's. Tom's hardware has a very interesting piece on the new 520 Intel SSD that sheds some interesting clarity on both those discussions (in the last few paragraphs). I thought it would be an interesting read.There is some limited discussion on "raise" that is being employed by many manufacturers.
