Well... The first try of slipstreaming was unsuccessful. I even used my OEM version of the CD, but I guess the folders that I decided not to include (PRELOAD, etc.) actually have the drivers I need, because when I booted it up, it didn't find hard drives on my PC. It found my external USB drive, but didn't find my internal drive :(.
I tried looking for the drivers from the Intel website and all I could find was an installer for the "Intel Matrix Storage Manager". I tried extracting it, but it just gave me the setup files, not the actual drivers. Nothing on the OEM cd looks like drivers, everything is in file types I can't open/extract.
I am pretty sure that the Tablet PC edition is Professional SP2, because of this article.
