I just received my OpenMoko FreeRunner phone and have been poking around in it, trying to learn my way around it.
I found this interesting:
root@om-gta02:~# cat /proc/version
Linux version 2.6.24 (build@barbie) (gcc version 4.1.2) #1 PREEMPT Thu Apr 24 08:23:36 CST 2008
Hmm... the FreeRunner ships with an Ingo patched RT kernel?
