Hi,
I'm running a Debian sarge on an iBook SE with a 2.6.5 kernel.
My iBook contains a "3D Rage Mobility L" and I've had some troubles with
the atyfb: my screen was turning blank.

I've modified the MCLCK and XCLCK of the "3D Rage Mobility L" in
drivers/video/aty/atyfb_base.c :

# old version
	{ 0x4c4e, 0x4c4e, 0x00, 0x00, m64n_mob_a, 230, 83, 125, M64F_GT |
M64F_INTEGRATED | M64F_RESET_3D | M64F_GTB_DSP | M64F_MOBIL_BUS |
M64F_MFB_FORCE_4 }


# new version
	{ 0x4c4e, 0x4c4e, 0x00, 0x00, m64n_mob_a, 230, 50, 50, M64F_GT |
M64F_INTEGRATED | M64F_RESET_3D | M64F_GTB_DSP | M64F_MOBIL_BUS |
M64F_MFB_FORCE_4 }


I don't know if these settings are rights for every architectures, but
for powerpc it is.

Thanks in advance

Arnaud FONTAINE

Yes those are the correct values. They are in a newer ATI driver I have. I 
looked at the default 2.6.5 code and it looks correct. Are you sure you 
are not using a modified driver?
