 Concerning your patches I believe that they will be valuable for many users
(although I could not verify them for me yet.). As I have found out flawed
EDIDs are a known problem and thatways f.i. already addressed by the
proprietary fglrx driver through letting the user select out of a prewritten
list of artificial EDIDs for known monitor types. Nonetheless just using the
EDID of another port of the same monitor or just suppressing the checksum test
promises to be a more gracile way of resolving such an issue. That is basically
why I want to make a commit request for these patches to be acquired in the
final openSuSE 11.4 release within 15 days so that more people can test these
options (mentioning them in the release notes with a demand to report the
results for finally acquiring the patches into the mainline kernel.). 
  As far as now I would also issue the following additional feature requests
for an in future comprehensively EDID relied graphics system:
(1) kernel option for using a user supplied EDID (instead of the hw. supplied
ED.)
(2) option(s) for Xorg or the radeon kernel module to achieve the same:
rebooting is painful and the typical user will have to test different things.
If Xorg quits without success in modesetting (as so often by 2.6.36.1-1) or
detects a wrong EDID checksum then it should point the user on the fgconsole to
try them.
  by the way: Do you know whether the nouveau driver does already fully rely on
KMS?
