Long filenames on vfat not working?

[S�ren Lamb�k]

Hi

When mounting a fat32 partition into linux (redhat 6.0) as a vfat filesystem it 
truncates long filenames til 8 chars.
It is not the "short DOS" filename with the "~" char that i get but the first 8 chars 
of the filename.

When booting the mashine on a dos floppy, the long filenames are ok on the DOS 
partition.

Any ideas as to what may be wrong

thanks from a linux newbie
