Don't missunderstand my little comment about that, of course I knew it was just about getting XPe going and your guide finaly motivated me to start over again with XPe, as I "throw it all away and gave up" the last time I tried on it.
So you definitely don't waste your time here, I'm shure it will make many peopel happy.
As you have ur car-pc 100% going (I assume with CF running?) many people may be glad if you'd list all the compontents and modules you used in the next tutorial. ;-)
