I am having some trouble with loading firmware drivers in Dom0 kernel.
The error I am getting when Dom0 boots up is

----------
ipw2100: Detected Intel Pro/Wireless
firmware_helper error loading /lib/firmware/ipw2100-1.3.fw for device
/class/firmware/000:02:2.0 with driver ipw2100
----------

This is the wireless nic driver of my thinkpad. It loads and works
just fine in my original kernel. When I checked the path it was
complaining about it was indeed not there but all the drivers seem to
be in /lib/firmware/2.6.17-10-generic/ which is my original kernel's
name.

Why isn't there an entry for my new xen kernel here? I am guessing
there should be something like /lib/firmware/2.6.16.29-xen/ here just
like there are two entries under   /lib/modules. (2.6.16.29-xen  and
2.6.17-10-generic).

I compiled xen-3.0.3_0-src.tar using make world, make install and install.sh.
I created an initrd using mkinitramfs -o initrd.img-2.6.16.29-xen
2.6.16.29-xen using Ubuntu 6.10.
If the firmware for ipw2100 remain the same under 2.6.16.29 => 2.6.17-10, you could simply copy (NOT move) the needed files in /lib/firmware/2.6.17-10-generic/ => /lib/firmware . Again, it may or may not work depending on whether the kernel module of ipw2100 has changed between version .16 and .17

You may want to submit a bug report to insure that the next xen kernel build for 2.6.17 has its firmware in the proper location.
