Seems to be F13/dracut issue in my case.

Xen 4.0.1-rc6 & 2.6.32.19 ( KMS  enabled) installed on top of Ubuntu 10.04
with no  problems.

I unzipped and uncpio  initramfs :-
      file is not there.
Tried --fware option of dracut. No luck.
File gets installed in /lib/fmware/radeon folder , but doesn't get
included in "initramfs"

It appears to be set to 'y'

> After that did you recompile the kernel and modules and re-installed them?
Yes.

How about -v? See if the file RV730_pfp.bin gets put in the initramfs
image. Did you make sure that the CONFIG_DRM_RADEON is set to 'm'? After
that did you recompile the kernel and modules and re-installed them?

You need to figure out why it isn't including that firmware file on the
initramfs.
