The first, 45MiB unallocated space must contain the boot loader and kernel image. Inside the file recovery_backup_signed.zip I found files uramdisk.img, recovery-uramdisk.img, and uImage. Running "files -s" command on these files on Fedora 15, I got this information:

uramdisk.img: u-boot legacy uImage, Android Root Filesystem, Linux/ARM, RAMDisk Image (Not compressed), 182088 bytes, Fri Sep 23 03:38:23 2011, Load Address: 0x90308000, Entry Point: 0x90308000, Header CRC: 0x6CD9AD84, Data CRC: 0xE99D6FFC

recovery-uramdisk.img: u-boot legacy uImage, Android Recovery Filesystem, Linux/ARM, RAMDisk Image (Not compressed), 958829 bytes, Fri Sep 23 03:42:05 2011, Load Address: 0x90308000, Entry Point: 0x90308000, Header CRC: 0x7EE613C2, Data CRC: 0x740C7563

uImage: u-boot legacy uImage, Linux-2.6.35.3, Linux/ARM, OS Kernel Image (Not compressed), 2941580 bytes, Fri Sep 23 02:05:50 2011, Load Address: 0x70008000, Entry Point: 0x70008000, Header CRC: 0x88FC0EBD, Data CRC: 0xD8FC49A0

So uImage is the kernel. All of them are probably located inside the first unallocated space. They are raw images, so presumably they don't need partitions.
