I use the repo RT kernel without patches but , but almost all the other music related stuff are compiled from sources. I also pass acpi=off to the kernel parameter (2.6.27-3-rt) in /boot/grub/menu.lst. My use of waf does probably do the same as you suggested, here is my configure recipe: PREFIX=/usr ./waf configure ./waf build sudo ./waf install. This way, 1.9 will replace your current jack installation. Some programs might probably complain because 1.9 do have a slightly different API, but my Ardour 2.7.1, Rosegarden 1.7.2, CVS version of the Linuxsampler apps and all important LV2 and LADSPA plugins works just fine, so I'm happy.
