Ubuntu 9.10 Server Grub2 does have issues with loading Xen Instance.
There are several well known workarounds.
1. Per PVops Wiki : adding dummy=dummy as first argument to kernel command line.
2. Build kernel with built-in command line.

I tested the grub2 and it's loading Xen instance normally. Below my configuration file:

# cat /etc/grub.d/40_custom
exec tail -n +3 $0
# This file is an Xen custom entries
menuentry "Xen 3.4 / Debian Lenny 5.0 kernel" {
  insmod raid
  set root=(md1)
  search --fs-uuid --set e795a163-5418-4ae9-8021-83fe9ce05ea7 
  multiboot /xen-3.4.gz dom0_mem=512M iommu=1
  module /vmlinuz- root=/dev/md3 ro console=tty0 pciback.hide=(06:0c.0)(06:0d.0)(06:0e.0)(06:0f.0)
  module /initrd.img- 

It was configured with xen 3.4.2 and without pvops kernel. I will try the xen 4.0.0rc6 and I will post the results.

What's wrong with native Grub2 ( it doesn't load Xen Instance ?)

 For the first time, I have the Xen 4.0.0-rc6 with Linux as my dom0 using the paravirt_ops.

 The Intel modesetting is working too!

 My xm info shows:

 To install the "tools", I need to run:

make install-tools PYTHON_PREFIX_ARG=

 And I'm using the Grub1.

 Now it is time to make a few domUs!
