Yay ! the Fedora5 image from jailtime.org has booted. Short version, I had
to run mkinitrd with ext3 support. Some issues remain - especially the failure
to load modules - see below log - and networking is not fully
functional.

Long post ahead if you are interested
My config
disk = [ 'file:/etc/xen/fedora/fedora.fc5.img,hda1,w' ,
'file:/etc/xen/fedora/fedora.swap,hda2,w' ]
memory = 256
vcpus = 1
builder = 'linux'
name = 'vm2'
vif = [ 'mac=00:16:3e:34:8f:88' ]
localtime = 0
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
extra = ' TERM=xterm'
#bootloader = '/usr/lib/xen/boot/domUloader.py'
#bootentry = 'hda6:/boot/vmlinuz-xen, /boot/initrd-xen'
kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
root = "/dev/hda1 ro"
In an earlier post you can see boot complains about ext3 when trying to read
the fedora5 image file.
I needed to include this in the initrd
