I have already tried, it does work, provided that the bootable flag is 
on the first partition. Unfortunately, fdisk does not allow me to 
replicate your desired partition tables exactly. I did want to swap 
partitions, but couldn't.

Here is the layout that I have tested:

MBR heads per cyl  : 64
MBR secs per head  : 32
MBR partition table:   N Status  Type        Start       Blocks
MBR partition      :   1   0x80  0x00            1        32803
MBR partition      :   2   0x00  0xef        32804         5760
