I can confirm, that wiping out the partition table (but not the boot
code), using "bsdlabel -B /dev/ad0s1", makes "s1" disappear.  Subsequent
boots can then be done from /dev/ad0a, and this works both for "old"
kernels, e.g. from before r186240 and after.

And at least VMware's BIOS isn't scared of empty partition tables. ;)
