There is one major point missing here.
The tool used by the distribution to generate the initrd for the installed 
system (for Debian initramfs-tools) will need to make sure the mmc driver 
modules are included in the initrd if the install is to an mmc device.

I have checked this, and for Debian in turns out they are included when 
the "MODULES=most" setting is used, so no problem for default 

I have bought a 2GB Sandisk Micro-SD card  (8 EUR here) and have just 
successfully completed an install, including bootloader installation 
after applying a few relatively minor patches.

There are no patches outside D-I required, so we could consider 
implementing this before Lenny.
I will send a separate mail with the patches.
