3Com OfficeConnect ADSL Wireless 54 Mbps 11g Firewall Router

This 3Com product has many functions: router, firewall, adsl modem, wireless access point, 4 port switch. 3Com chose to give two names to its products: a name for the market (as the long name in the title), which identifies the purpose of the product and is not changed when a new model replaces the older one, and a model name, a number which identifies the specific model.
The "ADSL" term in the name is particularly useful to specify that it's a adsl modem too, with a RJ-11 port that would connect the router directly to the phone line, through a RJ-11 cable, just like any adsl modem; in fact I found several routers that were capable of routing the adsl signal but were equipped with a RJ-45 port instead of a RJ-11 port: they were not DSL modems and needed to be connected to an external DSL modem. Checking the rear of the product, maybe on the user guide, can help making sure the router is a DSL modem too.
I will review two 3Com OfficeConnect ADSL Wireless 54 Mbps 11g Firewall Router models, the older 3CRWDR100A-72 and the newer 3CRWDR101A-75.

Running Windows XP in Xen from its own partition

Some months ago I made some experiments with Xen and I succeeded to install and run Windows XP as a guest using Xen 3.0. In that case Windows was located in a single file and was installed through Xen. My purpose now is to make Xen running an already installed Windows from its own partition. Just to be more specific, this is my machine configuration:

Ubuntu Dapper Drake 6.06 is located on a SATA disk, set as first boot disk
Windows XP is located on a EIDE disk, set as second boot disk
Dual boot is made by grub

I want to log into linux and run my existing Windows XP from its own partition on the EIDE disk.

Ubuntu Dapper Drake 6.06 amd64 and Windows XP in Xen 3.0

I am coming from a bloody week of wrestling against packages, bugs and "make world"s trying to run Xen in Ubuntu 6.06 amd64 on an AM2 3800+ and to make a Windows XP Pro domU.
I searched on the web some resources that would explain how to run Windows on Xen and I found some very good tutorial that unfortunately don't fit exactly my configuration and my purpose. These are the sites I took as a basis for my setup:

These are all the steps I did and the problems I encountered during this Calvary :-) (I come from Windows with a little linux/unix background):
