Yes, support for this was recently added.

As a general (not NetBSD-specific) issue:
I don't know if all controllers can handle it; the hack is to
write the count and sector registers twice before writing the
extended command code. If the command is refused, there should be
some kind of a fallback mechanism.

I don't know whether this is an actual problem or not, I don't know
enough about the low-level (electrical) details of ATA.
