I am currently trying the 2.6.22-rc1 kernel. I have it built and tests running 
on i686 machine.

I also built and installed it on x86_64. On the x86_64 I am seeing that things 
are dying in __register_kprobe when the module attempts to install the probes. 
Unfortunately this machine doesn't have serial port, so I will need to install 
the kernel on an x86_64 machine with a serial port so I can get traceback.

This also brings up the issue of configuration of the kernel the runtime does 
take into account what is availble in the kernel, e.g. CONFIG_DEBUG_FS and 
CONFIG_RELAY. Depending on configuration one kernel might work and another not.
