Will Dapper support RLIMIT_RTPRIO?

The new RLIMIT_RTPRIO was introduced in kernel 2.6.12 to selectively
allow non-root processes to run tasks with realtime priority.  This is
essential if we ever want reliable multimedia performance without
forcing users to run as root.

Supporting this new rlimit requires some changes to glibc, bash, and
PAM.  It was added to glibc 6 months ago:

Presumably Dapper will ship with a post 2.6.12 kernel - so will Dapper
ship with full userspace support for this new rlimit?

I checked the current glibc sources and these new RLIMITs are not yet
supported...
