[ubuntu] recently updated ubuntu kernel question

view story

http://ubuntuforums.org – so i had ubuntu , probably lucid lynx or another right around there, and had added the ubuntu studio audio packages. the other day, i updated to the latest ubuntu, and it also updated to the latest version of the us-audio packages. my question is, will the update have given me the ubuntu studio low latency kernel? how do i find out if it is so? and if not, how might i go about getting it ? (never compiled a kernel before :oops:) thanks for any help ):P (Hardware)
