/lib/firmware/2.6.32-41-xen (kernel pre-installed by ubuntu karmic) from
where did you get this ?
Actually, is it something providing by Ubuntu or you applied some special
patches ?

Thanks.
Boris.

I happened to run into this yesterday as well, but i don't think the
kernel is at fault here, you are simply missing the radeon firmware...

I solved it by creating a symlink from the /lib/firmware/2.6.32mh5 (the
version of the kernel i built) to /lib/firmware/2.6.32-41-xen (kernel
pre-installed by ubuntu karmic).
After that, recreate the initrd, and reboot.
For me the driver loads properly now, and i can run X.

It does however not enable MSI on my device (which i had hoped, since that
would resolve an IRQ conflicht I'm having with some PCI devices).

Regards,
Mark.
