PENGUINBAIT:

I am taking you up on your generous offer of support before I try this (in order to avoid killing my 810). I have further simplified your instructions just to make sure I do not screw this up:

You want me to get a SD Card with (at least) 2 GB on it. I have a Micro 2 GB card and can move the stuff off it so it is empty. I then copy the following 8 files to that card:

http://www.tablethacker.com/software/local-mmc1.deb
http://www.tablethacker.com/software/kde-3.5.8-mmc1.deb
http://www.tablethacker.com/software/kdesup-3.5.8.deb
http://www.tablethacker.com/software/KDE358.tar.bz2
http://www.tablethacker.com/software/local-mmc2.deb
http://www.tablethacker.com/software/kde-3.5.8-mmc2.deb
http://www.tablethacker.com/software/kdesup-3.5.8.deb
http://www.tablethacker.com/software/KDE358.tar.bz2

I then verify (only) the size of 6 of those files:

308317552 KDE358.tar.bz2
308126 kde-3.5.8-mmc1.deb
308122 kde-3.5.8-mmc2.deb
21260684 kdesup-3.5.8.deb
510560 local-mmc1.deb
510548 local-mmc2.deb

I then insert the Micro SD card into the slot and install 6 files in the SD Card in this order:

local-mmc1.deb
kde-3.5.8-mmc1.deb
kdesup-3.5.8.deb
local-mmc2.deb
kde-3.5.8-mmc2.deb
kdesup-3.5.8.deb

I then start KDE from extras menu.

I can then delete which (all?) of the original 8 files I put on the Micro SD card in the first instance?

Have I got this right, it sounds straight forward? I hope to hear back from you and thanks in advance.
