Only for your information regarding the current state of resmgr,
see the last section of
http://lists.alioth.debian.org/pipermail/sane-devel/2007-January/018351.html

My current disable-resmgr-support.patch (since since openSUSE 10.2)
is (some lines are wrapped here):

Regarding the HZ stuff, see
http://lists.alioth.debian.org/pipermail/sane-devel/2007-January/018479.html

The fixed HZ compile-time value (no longer supported by new glibc)
should be replaced by the more correct sysconf(_SC_CLK_TCK) runtime
value because a compile-time value works only if the compile-system
is the same as the runtime-system.
