It's highly possible that ramdisk.img actually is a compressed file ramdisk.cpio.gz. To extract it use this commands:

cd /Path/To/Folder/With/ramdisk.cpio.gz/File
mkdir temp_directory && cd temp_directory
gunzip -c ../ramdisk.img | cpio -idm

Just use p7-zip which is 7z just for POSIX.

7z e ramdisk.e RamdiskExtracted

I'm not sure about repacking and keeping metadata though.

I guess you could mount it as rw??
