Hi, I'm trying to use the video output on an iBook G3 2.2 14" equipped
with an ATI Radeon Mobility M7 LW [Radeon Mobility 7500] using a 2.6.7
Linux kernel and X.org's X11R6.7.0 x server. I'd like the external
monitor to clone the iBook's one.

Unfortunately if I follow these steps, the external monitor works
almost properly but the iBook's one doesn't at all. When I open up
the lid I get images that have nothing to do with the output I get
on the external monitor.
If I run dmesg give these conditions I get these lines among the
others:
radeonfb: Invalid ROM signature 0 should be 0xaa55
radeonfb: Retreived PLL infos from Open Firmware
radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=180.00 Mhz, \
System=180.00 MHz
radeonfb: Monitor 1 type CRT found
radeonfb: EDID probed
radeonfb: Monitor 2 type CRT found
radeonfb: EDID probed
radeonfb: Power Management enabled for Mobility chipsets
radeonfb: ATI Radeon LW DDR SGRAM 32 MB
If I just plug the external video cable but I don't close the lid
the iBook's monitor works, apart from not setting the resoulution
properly under X, and the external monitor doesn't work at all.
If I run dmesg give these conditions I get these lines among the
others:

I've been lurking the ML for a while and some time ago I read in another
message that someone managed to make the cloning to work. Unfortunately
I'm not able to find that message anymore. =( Furthermore I'm not a
Debian user thus I'm not able to use Debian binary packages.
I know this ML is intended for Debian users but I wasn't able to find a
community like this anywhere else and this is the only place where I was
able to find useful informations about running GNU/Linux on an iBook when
I needed an helping hand.
Any hint or pointer will be appreciated.
Thanks in advance.
Best regards.
