The right lists are xen-devel@lists.xensource.com (for development
questions) and xen-users@lists.xensource.com (for more general user
questions). You can sign up at http://lists.xensource.com.

The README assumes that you have no special /boot partition (i.e. that
the contents of /boot are on the / filesystem). As noted in the comments
at the top of your grub config, your system does have a special /boot
partition, and hence paths are relative to that.

The "path problem" looks ok with the below config (assuming that you
have files xen.gz and vmlinuz-2.6.10-xen0 under /boot). There are a
few other errors though:
(1) "kernel /xen.gz dom0_mem=131072 ro console=vga" ; xen doesn't
take a 'ro' option, so just remove that
(2) "module /vmlinuz-2.6.10-xen0 ro root=/dev/hda0"; you have a
bogus root partition (/dev/hda0) -- there's no such device.
Not sure what this should be; your FC3 install is using a
logical volume manager so you may be able to use this directly
(with relevant support in the kernel and/or initrd), or you
may wish to directly specify the 'real' partition if you're
not using raid.
(3) "module /initrd-2.6.9-1.667.img"; this initrd looks like it
belongs to the FC3 kernel and is unlikely to work with the
xen0 kernel.
You say the machine restarts very quickly; perhaps you should remove
the lines "splashimage" and "hiddenmenu" and see if you get any
console output. You may wish to add the option "noreboot" to the
"kernel /xen.gz ..." line if you find things rebooting too quickly.
HTH,
