hints on how to get this working would be appreciated.
The messages would be helpful. You did this by applying the normal
capabilities patch[1] by hand? I haven't tried that yet, because I've
been experimenting with Linux Security Modules.
Yep thats right.. Don't know what went wrong as it seemed to work when
I tried it the second time. I think I had set RTC as a module in kernel
and not sure if it was loading properly.. Also I had not set my MB
chipset in the kernel so everything was slow, so that could have been
adding latency problems.. anyway, it is working now. I can't get as good
latencies as you but then I am using a SBLive! Seems relatively stable
in full duplex at 2 / 512.
If you like to live dangerously, here's[2] a preliminary realtime LSM
for 2.6 you can try. It works with an unpatched kernel, but you need
kernel sources to build it and install it.

The module looks interesting. I think I will wait til it gets into the
kernel to try it though. (knowing me this will mean I will probably try
it out in the next few days!! ;) )
