And what is the lspci off the different hardware? What is the
diff between the original hardware and this hardware?

And you did follow the PVOPS Wiki on troubleshooting and using
"console=hvc0 debug"

No. The issue is (and I explained this to you on irc) is that the video
driver you have is an PCI/AGP type. The patchset to make the 2.6.38
(devel/agp.pci-api) haven't been up-ported to the 2.6.38 tree. In essence
the code to make this work is not there. The 2.6.32 has this code.

Uhh.. yeah that is expected. There are no patches in the 2.6.37 tree
to make it work.

You got three options:
- Stick in a PCI-e discrete graphic card. Say Radeon el-cheapo. See how
that works.
- Make sure to disable the MGA driver from the kernel and only use
the VESA/VGA framebuffer. That _should_ be working. If it is is not
please send an e-mail here.
- Back-port yourself the #devel/agp.pci-api in the 2.6.38 kernel.
There is going to be a compile fallout somewhere in the drivers/gpu/drm/intel,
but you could patch that over by just passing a NULL pointer.

My .config is basically using the Ubuntu 11.04 config will XEN_ options turned
into =y. But that won't help you in this case.
