Why are you trying to sensationalize this patch as omap4 specific? First, it doesn't just affect the omap4 kernel, it affects all kernels from Lucid 10.04 forward, on all platforms. And it isn't only limited to Ubuntu.
If it only affected the 11.10 release of Ubuntu on omap4, then there is nothing to worry about, as there are only >10K panda boards that this supports sold so far.
And yes, Ubuntu does update their kernels far more often than Microsoft, or even other Linux distributions. This kernel was released 11/23, and guess what? The next updated kernel is due out next week. With more glorious fixes for the masses using an omap4 based "system" from http://pandaboard.org.
What a joke.
