I was surprised when I saw it, I didn't remember seeing it the first
time. Another person answered here that when making the initrd image I
just try to ignore the aacraid option; so I was making the latest init
images with this:

mkinitrd -v -f --with=sd_mod --with=scsi_mod
initrd-2.6.16.29-xen.img 2.6.16.29-xen

instead of :
mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod
initrd-2.6.16.29-xen.img 2.6.16.29-xen

When I use mkinitrd just as the readme says (the second way) there is
no error loading lib/sd_mod.ko

I eat some words here, I don't know why. I have no a /etc/modules.conf archive.

I eat words again here, sorry. I did <mv /lib/tsl /lib/tsl.disabled>.

I tried to download Xen sources from Fedora page but I didn't find it,
so I'll use the second option
