AC'97 is for ex. in Lenovo ThinkPad T60 that was still sold in 2007. It is entirely possible that the same chipset was used in later models and maybe is still in manufacturing.
Quick search on http://www.bsdstats.org/bt/devices/class/04/subclass/01.html reveals that quite a few systems still use AC'97, particularly "82801AA 8xx Chipset AC'97 Audio Controller" is listed as used 631 times and in fact is the most frequently used particular type of the audio device listed on BSD stats website.
I only wish more people shared their hardware with BSD stats.
Also this T60 may be obsolete by the latest and greatest standards, but is still a very capable system, can easily run BSD or Linux and would be totally sufficient for someone who only needs to browse the web and check e-mail (read 95% of people).
