Need a realtime kernel distro
 

does anyone know of distro that comes with a realtime patched kernel?

Could you not get the Con Kolivas patched kernel to
compile?

Who?
 

the what kernel to install??? where do i get it?

search google for 'Con Koliva'. the first result is this.

Is there an iso or do I have to recompile?

it is just a kernel patch to lower latency in the linux
kernel. i don't think he wrote any of the patches, he
just collected some patches and put them together.
It's not a distribution, but i wouldn't be suprised if very
soon some linux distributions have these patches
built in, or have them as options.
no iso, you have to compile.

most 2.5.xx kernels have the preemptive bit in the code already.
