Man, that fixed background is annoying. Contrast is too high vs. the text (on my dtp-94 calibrated monitor).

IE9-only? No wonder I've never heard of this one. But it is in the spec, according to w3.org: http://www.w3.org/TR/css3-values/

Complain and it shall be (no longer) fixed!

Read: he heard you and now the background is no longer fixed. ;)
