2610SA sata raid array ... backported yet ? driver update package ?

[user]

I would like to use an adaptec 2610SA SATA raid controller with FreeBSD
5.4.

My research:

http://lists.ooz.net/freebsd-hackers/?mid=19018

shows that aac_pci.c has this in it for 6.0, and there were some plans to
backport it to 5.4 with a driver update ?

Does anyone know the status of this ?  I have looked in the 5.4 release
notes, and did not see anything - where else can I look for this ?

Thanks.
