That is what I would recommend and what several groups do (usually with Debian, though). > not running the sles/rhel distro ?

The only thing that really might cause trouble is udev, since sysfs maintainers like to break old udev versions. I think upcoming Debian Squeeze requires 2.6.27 at a minimum.
