Ok one problem that does exist is the partition table. RiscBSD does not 
understand MSDOS partition tables.
Although there is an MSDOSFS filesystem it needs the actual partition the 
filesystem is on.
With floppies there is no partition table as the whole floppy is always 1 
MSDOS filesystem so these can be mounted.
Harddiscs etc. that have partition tables will give problems as RiscBSD 
does no understand MSDOS partitions and thus cannot implement them so all 
you all you have is the /dev/xx?c which is always the whole disc.
What needs to be done is the disksubr.c code in sys/arch/arm32/arm32 should
be extended to recognise a MSDOS partition and to fake a disklabel that 
describes the DOS partitions.

Really this should perhaps be MI somewhere rather than MD as this is not 
just a problem from RiscBSD.
