For Debian the patch you linked to is not actually needed. Debian's grub1 uses the grub-install from grub2 and thus supports mmcblk devices. I have successfully installed grub to /dev/mmcblk0 after adding support for it in grub-installer. I tried testing it by chainloading grub on the SD card from the regular grub on my hard disk, but unfortunately the BIOS was not to be fooled (Error 21: Selected disk does not exist). So the reboot is untested, but I'd expect it to work on systems that do support booting from SD card. Of course that still leaves support for other bootloaders (lilo, other architectures).
