Russell,

Sched_clock is available very early during boot sequence. Initially gp-timer 
(dmtimer) will get registered as a clocksource. Please refer to the file
mach-omap2/timer.c

32k_sync timer (omap-32k.c) will come get registered during arch_init.

Just FYI, the way I tested it is, I used kernel parameter 
"clocksourse=counter-32k", the switch from gp-timer to 32k timer
will happen once it gets registered.

Thanks,
Vaibhav
