Secure disk erasing

I was looking at wiping a disk and found the following:
http://blogs.zdnet.com/storage/?p=129

in particular Secure Erase
http://cmrr.ucsd.edu/Hughes/SecureErase.html

Which talks about using a function built into modern drives.

from the readme:
"It offers the option to run the drive internal secure erase command,
security erase unit, based on the ATA specification by the T13 technical
committee."

Is this function available via OpenBSD?

Cheers
