No seriously:
Without having a ppc machine, I imagine that you can hit escape or any key
during boot, so that you get the boot loader's option menu, and move the
cursor to the previous kernel entry, hit enter...
As long as the older working kernel is still installed, it should be enough
to yum remove kernel.specific.bad.version, and the rpm should take care of
setting the previous versions item as the one to boot.
And after booting the old kernel, "yum erase" will remove the offending new one.
For Fedora 11 the default maximum number of kernels for yum to keep
installed is set at 3. The two prior kernels plus the broken one
should be available.
Now, if you really care about what is happening to your system during
boot I recommend that you edit /boot/grub/grub.conf (alias menu.lst).
Comment out the "hiddenmenu" line (put a '#' in front of the 'h').
This will allow the other installed kernels and/OS's to be displayed
as selectable boot options. (Increase the number in the "timeout="
line if you want more time at making a selection.) Delete "quiet" and
"rhgb" from all the kernel stanzas if you want to see additonal
details and status of drivers and services during the boot process.
About the only thing I think is really needed is the timeout increase, since
once you get the menu up by hitting a key you can do the rest. I also want more
than 3 old kernels, I'd increase that one as well. Deleting rhgb is a good idea
with some video hardware, for sure, unless I have problems quiet is fine, I just
want to know if there's a problem.
