The latest chrome beta checks Build_ID in the build.prop to ensure compatibility. Up until now tenderloin was building with a GB Build_ID which broke chrome compatibiltiy. This is now fixed in mainline CM9 code (see my patch here: http://review.cyanog...m/#change,13008) for future builds.
However, on Alpha 2 (which is where you should be for hw video decoding) the fix is to edit a line in build.prop. Replace "ro.build.id=GWK74" with "ro.build.id=IML74K". (Fix taken from here: http://tinyw.in/fSAb)
For those not comfortable doing this I made a flashable fix for it. Just flash the .zip in recovery over alpha 2.
