Yes, it does have problems... that said, I don't know which
versions have problems, and what size it starts to be a
problem, etc.

Hmmm, further parteding is ok.  Perhaps I should say this...

Oops, you're right (almost).  /me wonders what he was thinking.

Just, there's important metadata that you'd be overwriting, so
it's quite a bit more tricky than that.  Still dd'able,
though ;-)

Anyway, if my calculations are correct (unverified):

        # dd if=/dev/hda1 of=fat32-start bs=512 count=4
        # dd if=fat32-start of=/dev/hda1 bs=1 count=3
        # dd if=fat32-start of=/dev/hda1 bs=1 skip=$[0x5a] seek=$[0x5a] 
count=$[420 + 3 * 512]
