A few articles are popping up around the traps on upgrading to the latest test 2.6.0 linux kernels. Over at kerneltrap.org, they take us through updating a system from a vendor neutral point of view.

Also over at Redhat, there are some unofficial kernel rpms as well, which can get installed with APT, if you have it installed on your system.
