It appears hiddenentry is a downstream feature only, sigh: https://build.opensuse.org/package/view_file/openSUSE:Factory/grub2/grub2-Add-hidden-menu-entries.patch?rev=135 It is still a bug in the petitboot parser though, as grub2 accepts {} for everything, even "true {true}" is valid. It's treated like quotes, it continues until the end is found and just treats it as arguments. I agree that not installing 95_textmode on PowerPC is a good workaround for the time being.
