Hm, I'm afraid I have no idea why you can't boot from second slice. Still, I 
would try fiddling with boot0cfg(8) or restoring boot manager - see 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/troubleshoot.html#BOOTMANAGER-RESTORE
but do that from the most recent installation that you have on slices (if that 
is the one on ad0s2 then perhaps by entering sysinstall from install cd). You 
did manage to make your backups by now of course?
