Its not tricky, I mean even I can do it, come on
I did edit a wiki page on this, but appears to be down, so here goes, from memory.
Backup any data first, just in case, not taking any responsibility for loss of data.
Firstly ensure your SD card if formatting correctly (FAT32), use on Gparted (linux live CD) to do this, (for me, I created two ext 2 partitions as well as I thought this would work best, works for me).
You then need the HaRET application to allow you to run Android. Google "haret.exe"
Extract the files this should create the right directory.
You then need to choose a build, this is personal choice, but I'll post the one I am testing right now. milanche's CyanogenMod 6 Kaiser
Put the installandroid.tar into the folder you created above.
Move to your SD card.
Find and run HeRET.
When screen shows text, tap and hold the center of the screen until you get a menu.
Choose install (ensure the options are set to SD).
Once done, select Quit.
This then installs Android and can take a while, just leave it to get on with it.
You should then been booted into Android.
I might have forgotten something, as I am doing this from memory, but it should be fresh since I installed this last night.
