$ /sbin/fdisk -lu ~njh/qemu/sparc/debian.img
...hopefully this displays the slices/partitions...

test.raw1   *        2048     1026047      512000   83  Linux

$ mount -o loop,offset=$((2048 * 512)) /mnt
(The offset is calculated by taking the start block number from fdisk
and multiplying it by 512 bytes)

$ ls /mnt/boot
...there should be a vmlinuz and initrd, you could check the silo.conf
or other boot configuration if you don't know the exact kernel/initrd
filenames.

$ cp /mnt/boot/{vmlinuz,initrd} /tmp
$ umount /mnt
