If it supports RDB, it should support booting (older? versions of) FFS in KS 1.3. If it doesn't though, just create a tiny OFS boot partition that loads the filesystem and immediately hands everything over to your main Workbench partition.1.2/1.3 can handle OFS only (old file system), so Your CF card should be formatted using this file system. FFS will not work..
