This may be a bug in the way sysinstall handles huge numbers.

Try using fdisk, bsdlabel and newfs without relying on the sysinstall
interface, i.e.:

1. Install a single slice covering the entire disk:

	# fdisk -I /dev/da0
	******* Working on device /dev/da0 *******
	fdisk: invalid fdisk partition table found
	# fdisk -I /dev/da0
	******* Working on device /dev/da0 *******
	#

2. Install a new label on da0s1:

	# bsdlabel -w /dev/da0s1

3. Edit the label.  Keep in mind that in 5.X the 'c' partition covers
only the `useful' area of the disk, so you don't have to leave some
unused space at the beginning of da0s1c when you set the size of the
da0s1a partition:

	# bsdlabel -e /dev/da0s1

4. Create a new filesystem on da0s1a:

	# newfs /dev/da0s1a
