I think, that someone told to you that you must use current ;-)

Anyway here you can find something about AHCI and SATA
http://en.wikipedia.org/wiki/Serial_ATA If you don't have option to
turn AHCI on in your BIOS then you may have problems. If you will read
this
http://www.openbsd.org/cgi-bin/man.cgi?query=ahci&apropos=0&sektion=0&manpath
=OpenBSD+Current&arch=i386&format=html
then you will know that AHCI simulate SCSCI and that's why your disk
will be sd then.
