Move PCI device scanning to dom0. Enable ACPI in dom0. This should greatly
reduce the complexity of xen and move the complexity of dealing with
hardware bugs and workarounds etc to dom0.
I've applied this patch on my T41p and am using it right now. Here are
the results so far:
1) Everything builds and loads properly, the ibm_acpi drivers enables
most of the /proc/acpi/ibm entries it's supposed to and they seem to work.
2) I get an oops during startup (doing USB coldplug), dmesg is attached
3) I don't seem to be getting proper battery status (it's always being
reported as 0%)
This work looks really promising. Thanks :-)
