In the bootloader-configuration screen you can move with <up>/<down> and <tab> key to the different options. Using the <down>-keys uses the order "Do not install a boot loader" -> "Kernel Parameters" -> "Force use of LBA32" -> "/dev/hda Master..." This is unexpected because <down> moves to elements being _above_ the selected one. I will attach an image plotting this issue.

Yes, this problem exists. Can't fix in the current timeframe, though. Deferring to a future release.
The behavior seems to work correctly now, although I didn't change it. Perhaps someone else did and forgot to close the bug report. Anyway, it works with the latest build.
