Yes.

1. Create a second partition with fdisk or cfdisk. Mount the partition
and copy preseed.cfg to it.
2. Boot into the installer. Select expert mode from the Advanced menu.
3. Press TAB and add file=/mnt/preseed.cfg to end of the displayed
command.
4. Boot the kernel.
5. At the first screen switch to a console (ALT-F2). 'ls -l /dev/sdb*'
should help identify the second partition on the USB stick. Mount
this partition; e.g: mount -t vfat /dev/sdc2 /mnt.
6. Proceed with the install.

As above, but make sure the third partition starts after the end of the
first partition.
