Radeon driver challenge - the Acer Ferrari 4000 laptop

[Alan Coopersmith]

If anyone who knows the Radeon driver is at the X.Org conference this week,
and feels like debugging it on challenging hardware,  I'll have a Acer
Ferrari 4000 with a Radeon Mobility X700 that seems to stump the Radeon driver.
(At least in part it seems the four outputs are confusing it - it has panel,
  VGA port, DVI port & S-Video port.)

The problem that generates the most widespread complaint is that it can't
seem to find it's builtin panel unless you put Option "MonitorLayout" "LVDS,CRT"
in it's xorg.conf file.   Without it, the probe logs these results, but
leaves the panel black:

(--) Chipset ATI Mobility Radeon X700 (M26) (PCIE) found

You can find a number of reports of this when searching for "Ferrari 4000 Xorg"
in google, including:
	https://bugs.freedesktop.org/show_bug.cgi?id=5473
	http://pages.cpsc.ucalgary.ca/~weckerl/ferrari_ubuntu_64.html#graphics

Other issues with it include:

	- Inability to use external monitor if you plug in the connector
	  after power-on if you have newer BIOS versions installed.

	- Getting the DVI to do something other than Panelsize regardless
	  of the Mode setting (so when switching to 1280x1024 on an
	  external DVI connector you get 1280x1024 stretched to 1680x1050
	  by the Ferrari scaled back to 1280x1024 again by the monitor)
