Last time I tested it the problem still exists using the 686 kernel on my machine. Using the 386 kernel, it brings up the dialog and shuts the system down properly. Using the 686 kernel the powerbutton kills the power.

My workaround for this is to add acpi=force to the boot parameters when using the 686 kernel. Which I have to redo in grub's menu.lst after every kernel update.

I suspect it's a hardware-specific bug, but I have not tried it on other hardware to narrow it down.
