what broke chrome flash?

[Neal Becker]

f17.  Was using nvidia + google-chrome-unstable.

Somehow, today flash doesn't work.  chrome about:plugins says:
Adobe Flash Player - Version: 11.5.31.1
Shockwave Flash 11.5 r31
Name:	Shockwave Flash
Description:	Shockwave Flash 11.5 r31
Version:	11.5.31.1
Location:	/opt/google/chrome/PepperFlash/libpepflashplayer.so

 	 Disable

.spl

1. yum remove xorg-x11-drv-nvidia.  Reboot.  Back to nouveau.  Still no flash

2. yum remove google-chrome-unstable.  yum install google-chrome-beta.  Still no 
flash.

I don't know what else to try.
