first is a small vfat with copies of the boot files from the CDROM (isolinux, install,.., but not the dists). copy install/isolinux.cfg to syslinux.cfg and run syslinux.cfg
second partition is >= 720 MB. copy the CDROM blockwise (dd ...) into that second partition.
boot the usb stick. It will complain that it does not find the CDROM. continue and skip the option to load additional drivers.
It will ask to manually enter the CDROM device. Use the second console to determine the device path of the partition
(e.g. /dev/sdb2) and enter.
OK, it works that way:
USB stick needs two partitions.
