Hi all,
I recently discovered a new option for radeon and r128 driver in Debian xorg
package:
Option "VGAAccess" "boolean"
Tell the driver if it can do legacy VGA IOs to the card. This is necessary for
properly resuming consoles when in VGA text mode, but shouldn't be if the
console is using radeonfb or some other graphic mode driver. Some platforms
like PowerPC have issues with those, and they aren't necessary unless you
have a real text mode in console. The default is off on PowerPC and on on
other architectures.
When set to "off", It solves the issue of secondary radeon card messing up the
primary one while reinitiliazing.
Those patches are extracted from freedesktop.org xorg CVS HEAD and are
registered in bugzilla.
See : https://bugs.freedesktop.org/show_bug.cgi?id=2064 for radeon
and: https://bugs.freedesktop.org/show_bug.cgi?id=2089 for r128
Cheers, Cedric
