Hey Fernando,

I didn't try planetccrma-core-edge package.  I've never used the edge
stuff; I'm too cowardly.  Not that it would really matter if my system
were unstable, but I'm just too comfortable with the regular stuff.

Here's the scoop on planetccrma-core:
[root@boon paul]# rpm -q --requires planetccrma-core
kernel-i686 = 2.6.16-1.2080.13.rdt.rhfc5.ccrma
kernel-module-alsa-2.6.16-1.2080.13.rdt.rhfc5.ccrma-i686 = 1.0.11-1.rhfc5.ccrma
alsa-driver = 1.0.11-1.rhfc5.ccrma
alsa-lib >= 1.0.11-3.rc2.2
alsa-lib-devel >= 1.0.11-3.rc2.2
alsa-utils >= 1.0.11-3.rc2
alsa-tools = 1.0.11-1.rhfc5.ccrma
alsa-firmware = 1.0.11-1.rhfc5.ccrma
alsa-oss = 1.0.11-1.rhfc5.ccrma
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1

I get 5.8ms latency with my Delta 66.  That's good enough (for now).
I've only record one track at a time, without any plugins.  Hardware
monitoring.  This is in Gnome, too.  I changed the pci latency value
to the max for the Delta 66 with "/sbin/setpci -v -s 00:0a.0
latency_timer=ff" but I'm not sure it helped anything.
