Hi,
While I'm looking over this, do you have a mode in which
the AHCI driver loads successfully?  If so, look for a
kernel message similar to this one:

ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 4 ports 1.5 Gbps 0x5 impl SATA mode

and post it, please.  (I think that it won't say "SATA mode".)
The "prog-if" value of 80 from your lspci output is interesting to me:
0000:00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03) (prog-if 80 [Master])

Thanks,
