NOTE: I've added some some more details to this entry and corrected an error regarding which bugs affected which rows.
The first Acid2 fixes were in build 7570. According to the W3C CSS 2.1 spec., min-height/width declarations take precedence over max-height/width declarations. In Opera, max-height/width won. Check this test case to see how your browser does for max/min-height and this test case to see how it does for max/min-width. In build 7570, we fixed the case where max-height overrides min-height. This fixes the height of row 1 in the Acid2 test. The max/min-width fix probably will not be in 8.0x, as it isn't part of the Acid2 test.
The second bug fixed in this build is related to the background shorthand property. If a declaration has more than one value for the same property, all values for that property should be ignored. Opera was using the last value found for background-color, background-repeat, background-image, and background-attachment declarations instead of ignoring all values. This fixes the coloring issue in row 13. Check this test case to see how how your browser does it.
Here's the updated rendering with these two bugs fixed:

Hey Tim,
Thanks for the running commentary. I really don't know why we all love to follow along. I've found a lot of the hysteria around Acid2 rather disturbing, many people missing the point completely — thinking it is a competition for alternative browser manufacturers or thinking Acid2 is the test to end all tests (it certainly ain't)! And yet, I followed along to the Safari fixes with fascination, and I'll do the same here. I suppose it has created a stir which can only be good, and as it appears most alternative browsers are going to fix many / all of the Acid2 bugs that means that hopefully the pressure will ratchet up on MS. I think there should even be an Acid 1.5 for other less exotic things already supported by alternate browsers but not by MSIE/win.
Look forward to more updates, can you please tell us which of Ian's bug test cases each Acid2 fix was derived from?
Sorry, small clarification
In my previous comment I meant can you keep linking to Ian's fixes for future posts — rereading it I see it looks like I'm asking for you to do something you have indeed already done, sorry :O ;)
I plan to. :)
