Welcome back! :-)

Actually, i used both the PlanetCCRMA and the "combined" (CK +
PlanetCCRMA) kernels for a while. The thing is, the disk I/O performance
is simply not enough. I'm using my system for all sorts of video stuff
too, not just audio, and the disk subsystem tends to be used pretty
Also, it's strange, but neither of these kernels has an overall desktop
responsiveness that i could rely on. Probably due to the unusual
workloads i'm throwing at the system.
Another thing, with these kernels, no matter which media player i use
(Xine, Gxine, Ogle, Goggles, mplayer...), the CPU load is very high when
playing any sort of video file. I tried anything i could think of: AGP
stuff, Xv, whatever. Nothing could fix it.
(My system is an nForce motherboard, with a GeForce2 embedded; i'm using
the "official" nVidia drivers)

So i went back to the plain Red Hat kernel. Amazing disk I/O, while
keeping the system extremely snappy under (my kind of) load. The media
players can play any video at ~1% CPU load.
However, it lacks capabilities, as i discovered today when trying to run
ReZound. :-(

So, i guess i'll give a try to your Red Hat + capabilities kernel.
