Comment(by Quozl):

 When did the initramfs begin using the file name?

 Can you enable flattened device tree support?  If so, change the ramdisk
 so that it does not contain the pattern "$bootpath in\n\t\t/sd@", which
 will cause the firmware to place this in bootpath:

 {{{
 /sd/sdhci at d4281000/disk:\boot\runos2.zip//ext2-file-
 system:\boot\runos2.zip
 }}}

 You can simulate this with manual booting:
 {{{
 ok patch exit /ramdisk fixup-bootpath
 ok boot
 }}}

 On 13.1.0 this causes a panic because the root filesystem is not found.

 [http://code.coreboot.org/p/openfirmware/source/commit/3350/ svn 3350]
 added support for older operating system releases which inspects the
 uncompressed ramdisk.

 The substitution done in ''fixup-bootpath'' loses the tail of the string.
 There might be a way to avoid that.
