Is it possible that this is a initrd problem?
I found out that device initialization is done before running /sbin/init 
(which includes running running /etc/rcS which includes mounting sysfs).
I also found out about the FIRMWARE_IN_KERNEL config. The Ubuntu kernel 
leaves this unset.

Is it possible that the kernel tries to initialize the device when 
running the initial ramdisk? Then it seems natural that it can't find 
the firmware because it is not included as I found out with:

file-roller /boot/initrd.img-2.6.30-020630rc8-generic

So I guess this is an Ubuntu bug about initrd/firmare configuration?

Thank you.
