Description of Problem:
Bug 70190 contains a patch for kudzu, which fixes a NULL pointer
dereference when monitor does not report hsync/vsync values, and
it is not in MonitorsDB. Because the VESA DDC code maps memory
to first 1M, kudzu does not crash, but reports hsync/vsync
in range about -2e9. This has been worked around in anaconda, but
the underlying cause has not been fixed. Please see 70190
for an example and an patch.
Same in phoebe.
I hope this will be fixed before summer betas ;-)
I don't know what bug 78284 says, but the patch is in rhlinux.redhat.com
Gee, I can't even mark it as duplicate ;-)
