11.2 actually still crashes randomly for me, too, even with disabling
the HW acceleration (Bank of America's one-time-use credit card
generator for example does not work anymore...) I was thinking mostly
of video playback problems (the blue tinted video, etc) but forgot
about the other crashing I experienced...

You can get old ebuilds from the portage CVS interface and drop them
into a local overlay.

From what I read, there will be no further releases of flash for
linux, except for the chrome-embedded version, so we may just be stuck
with this broken version, to use chrome, or forced to downgrade to an
insecure version (I'm sure this one is insecure, too, they just
haven't found it yet...)
