A workaround is to create a smaller casper-rw with the GUI and then make it larger. It's still constrained by the 4GB vfat limit, though. For example, to increase it by 1GB:
dd if=/dev/zero bs=1024k count=1024 >> /media/disk/casper-rw e2fsck -f /media/disk/casper-rw resize2fs /media/disk/casper-rw
I increased mine to 3GB this way, with no apparent problems.
