In linux, sure, there are two drivers for Marvel Yukon cards, called
skgeinit and sky2. This is FreeBSD though, which has drivers called sk
and msk. If you check the man pages for those drivers, it even tells
you the history of when those drivers were added to FreeBSD.

I think that the two drivers support different chipsets, so neither is
'default'. msk(4) was added in 6.3, so backport to 6.1 might be
possible - have you tried taking the driver from 6.3 and compiling it
on 6.1?

6.1 is no longer one of the 'supported' branches of FreeBSD, you may
consider upgrading to a version that is.
