I suggest using file: instead of tap:aio (I haven't tested this, but it's been said here or elsewhere several times that it is faster than tap:aio) I've been using it all the time with good results.)
the tap driver is quite a bit faster than what file: does (file: mounts the file as a loopback device, and passes in the loopback device to the DomU. the tap driver directly manipulates the blocks in the file.)

You do not need that, comment it out.
You need that if you are not using pygrub.
Btw: *why* do you want to use a jailtime image if you can just install/kickstart a CentOS 5 VM in no time?
I agree this is probably the best course of action if you want CentOS 5. virt-install will give you a working system with pygrub (and I think pygrub is keen.)
