Ah, hold on -- I see what the 'fix' was.   The black-screen bug was put into the release notes by Robbie, which doesn't fix the bug, but does at least have it documented for Maverick.  This is consistent with Andy's comments.

This bug will need to be moved to Natty Narwhal (11.04).  If a kernel
fix is found, it can be back-ported to Maverick and included during a
normal kernel update.

It's important to note this problem has been with us since Lucid, and a
kernel fix may be available in the wild.    The underlying issue is the
detection of the main screen (LCD device tags).    One of the relevant
patches was submitte by Alex Deucher, and he's continuing the work to
fix the support for different kinds of panels/connections in the radeon
code (e.g):
