Pkg xen devel - Dec 2010 - Bug#600241: #600241: Xen Hypervisor can only boot if "acpi=off" parameter is used.

It's hard to tell without full logs but since this is a Dell 410 there
is a possibility that this is the same bug as #603632.

Please test with kernel 2.6.32-29 when it is uploaded (which should be
later this week).

If this does not help then please provide a full log of the boot.

Ian.
