Public bug reported:

Binary package hint: xorg

Using 11.04, and flash videos are completely unusable, as short while
after you started watching them your CPU gets so hot that the
performance drops too much.

This happens much faster if you use full screen mode.

I am trying to figure our what driver I am using, but using glxinfo just segfaults. Attachment contains a strace for the segfault.
I have ATI Mobility Radeon X1300.
