Hello,
I'm having one silly partition, which has remnants of previous FAT32 filesystem
on it, a LILO bootloader on it and ext2 filesystem spaning all over the
partition.

The first 512B look exactly like a valid FAT partition header would, except the
magic is "LILO". 

I've looked at the sources for FAT detection, and I noted that when a FAT-like
filesystem misses magic, it's still considered valid, since as comment says,
some old floppies may lack it. I consider this point valid, however, this
causes my partition to be detected, incorrectly, as FAT32.

My proposed solution is to compare magic if FAT32 is assumed, and if magic will
not match for FAT32, consider it a failure; floppies that old that they lack
any magic will most likely not be formatted in FAT32.

Trivial patch is attached, comments/complaints?:)
