Here are my working grub.conf entries for pv_ops dom0:

VGA text console:

title Fedora Xen pv_ops dom0-test (2.6.31-rc5)
        root (hd0,0)
        kernel /xen.gz dom0_mem=1024M loglvl=all guest_loglvl=all
        module /vmlinuz-2.6.31-rc5 ro root=/dev/mapper/vg_dom0test-lv01
        module /initrd-2.6.31-rc5.img


Serial console:

title Fedora Xen pv_ops dom0-test (2.6.31-rc5) / serial console
        root (hd0,0)
        kernel /xen.gz dom0_mem=1024M loglvl=all guest_loglvl=all 
com1=19200,8n1 console=com1
        module /vmlinuz-2.6.31-rc5 ro root=/dev/mapper/vg_dom0test-lv01 
console=hvc0 earlyprintk=xen
        module /initrd-2.6.31-rc5.img

When using serial console with Xen you don't need to specify serial console 
stuff for the dom0 kernel..
Also note the 'console=hvc0' for dom0 kernel..
