Yes, you're right and now I think I know what may cause this bug and it 
worries me even more -- my FAT32 partition has a funny name but it for 
sure was not like this before:

$ ll /dev/msdosfs/
crw-r-----  1 root  operator    0,  95 Jan  3 09:28 FREEDOS
crw-r-----  1 root  operator    0, 103 Jan  3 09:28 01wb?

Here's the complete output you asked for:
http://mato.gamato.org/freebsd/aw1n/kern.geom.confxml-8.0

Cheers,

Martin

PS: I've just read about some msdosfs issues and I'm very much worried 
that my partition data might be corrupted. :-/
