I found that 2.6.24 needs the patch "[PATCH] Fix powerpc vdso
clock_getres()" posted February 8th on linuxppc-dev (which I missed,
sorry for the noise).
That seems to fix it in a quick test:
root@mpc8313e-rdb:~$ /timers
Clock resolution (clockid 0): 0.000000001
Clock resolution (clockid 1): 0.000000001
