I got it working, with Chimera 1.4.1.
First, I cleared the SSD and installed Lion. Then, I ran MultiBeast 3.8 (UserDSDT). Then, I installed Lion again on the same drive, and I ran MultiBeast again, only for network, audio, and disks. Finally, I ran the latest MultiBeast for TRIM support and to move kexts to S/L/E.
