Yes, this fixes the problem! Now xen-tip/next pv_ops dom0 boots OK for me,
just like dom0/hackery did earlier!

But there's more.. I was pretty surprised when I booted up my testbox, 
using the serial console as usual, and in the end of the boot process login
prompt (getty) appeared on the VGA text console (tty1) !!

It seems this (or some other) patch has fixed the 32bit pv_ops dom0 console 
problems aswell.. 

Next I tried without the serial console, and yes, now the VGA text console 
works just like it does with the old 2.6.18 xenlinux tree! I can see the
pv_ops dom0 kernel boot messages after Xen boot messages just fine.

My grub.conf:

title Fedora Xen pv_ops dom0-test (2.6.30-rc3-tip)
        root (hd0,0)
        kernel /xen-3.3.gz dom0_mem=1024M loglvl=all guest_loglvl=all
        module /vmlinuz-2.6.30-rc3-tip ro root=/dev/vg00/lv01
        module /initrd-2.6.30-rc3-tip.img

No need to specify console= or earlyprintk= anymore!

Thanks for all the hard work and congratulations!
