There is PowerPC genTOD patch and it's incorporated into -rt (don't know it works for Cell) but it breaks TOD vsyscalls. Several months ago I've posted patches removing them for the time being:
http://ozlabs.org/pipermail/linuxppc-dev/2006-November/027686.html
and I've heard that this issue is being worked on now by John Stultz. Here's also a patch implemeting read_persitent_clock():

Note that there *is* PowerPC clockevents driver already (don't know if it works for Cell) -- it just never got merged to -rt:
