Thanks Till. I tested a few more mainline kernels, including 3.8.3, 3.8.4, 3.8.5, 3.8.6, and 3.8.8. Unfortunately, mirroring also doesn't work properly with any of those tested mainline kernels. So at present, at least for me, the only relatively recent kernels that properly support mirroring in Ubuntu 13.04 on my AMD Radeon HD6670 are:

Ubuntu 3.8.0-7-generic
Mainline 3.8.0

I hope to perform a clean install soon after Ubuntu 13.04 is officially released. If this bug hasn't been fix by then, I'd like to revert to one of the above kernels after the clean install. But unfortunately, if Ubuntu 3.8.0-7-generic isn't readily available for download at that time, I'll likely be forced to use mainline 3.8.0. So here's hoping that older (pre-release) Ubuntu kernels will be available after the official release of Ubuntu 13.04.
