I needed to do this last year, and the instructions from Richard Elling 
were close to what you asked (the same except change the BIOS mode first):

0. change BIOS setting to AHCI
1. boot livecd with shell login
2. import rpool
3. export rpool
4. boot

The only extra complication I found is that if you have pools with cache 
devices then you need to remove/add the cache devices to make things 
happy, but otherwise this should work.
