 The initrd on fc6 is fucking broken. It doesn't have xenblk or xennet added. The reason I think is that initrd is created dynamically and the code doesn't have the --preload=xenblk. This is the actual command you have to run to get a proper initrd.

echo "/dev/sda1               /                       ext3    defaults 1 1" > myfstab
mkinitrd -f --with=xennet --builtin=aic7xxx --builtin=serverworks --preload=xenblk --omit-raid-modules --omit-lvm-modules --fstab=myfstab  /boot/xen-initrd.img 2.6.19-1.2895.fc6xen

 (Command courtesy of Jerry from xen-users, slightly modified by me).
 This will fix everything.

 Thanks.
