With the last X update, some non-free code has been revomed, and source
patched accordingly. X itself does not handle the load of the microcode to
the board, the kernel does (therefor i am reassigning the bug).
For completness I did a check on the radeon code inside X and there is no
reference to radeon_cp_load_microcode or similar calls. On the other side
that can be spotted inside the kernel at:
kernel-source-2.6.5-2.6.5/drivers/char/drm/radeon_cp.c:675
/* Load the microcode for the CP */
static void radeon_cp_load_microcode( drm_radeon_private_t *dev_priv )
[SNIP]
that is called twice in the same file. Specifically at lines 1258 for
radeon_do_init_cp and 1339 for radeon_do_resume_cp.
X uses these two functions via ioctl but cannot disable the
radeon_cp_load_microcode itself.
Herbert, would you be so kind to take a look at this patch?

It should be able to fix the problem but i cannot test it myself since I
lack that kind of hardware.
Thanks a lot
