Use two 40GB FAT32 files system instead. First you will need an MBR,
I assume you doing this from an intel NetBSD so that should not be a 
problem.
	fdisk -if xxxxx
	 fdisk -iu xxxx
and set parition 0 and 1 to be both 40Mb
you might then consider disklabeling (fot netbsd's benefit)
but make sure the partitions defined above do not use the first
"track" work of disk. (so the partition will be 40Mb-(track/2))
   them
	newfs_msdos xxxxxa
	 newfs_msdoa xxxxxb
or whatever partition disklabel thinks they are (maybe e and f -
I play with non-intel boxes so I'm not certian)

Note the MBR created by WindowsXp (not any other windows) is not
quite the same as expected by older NetBSD (or anyone else) but
WindowsXp will read to old (standard) MBR. So do this on NetBSD.
