Now that I know that HIGHMEM is not required, except it I have a domX
over 1Gb, I''ll turn it off.

I was using usb for loading data via usbstorage. I can probably remove
that.
By default hotplug runs this is the basic module list.
nic@stateless:/usr/src/xen/xen-2.0.bk$ lsmod
Module Size Used by
ohci_hcd 17288 0
usbcore 107512 2 ohci_hcd
ipt_state 1664 12
ip_conntrack 41364 1 ipt_state
iptable_filter 3200 1
dummy 2308 0
ip_tables 17024 2 ipt_state,iptable_filter
rtc 13240 0
Without hotplug running its:
nic@stateless:/usr/src/xen/xen-2.0.bk$ lsmod
Module Size Used by
ipt_state 1664 12
ip_conntrack 41364 1 ipt_state
iptable_filter 3200 1
dummy 2308 0
ip_tables 17024 2 ipt_state,iptable_filter
rtc 13240 0
Even with hotplug stopped, still get the same level of intrs.

That was the next plan.

No, I figured it was better not to post the config.diff to the list.
