Thanks for that and 70203b as well. I think there's a bug. I tested 70203a in a VM. The first time I ran it my power got interrupted while it was installing, so that may be a factor. However, it occurred during GUI-mode setup, not txtmode copy. After I restarted setup, I got a bunch of error boxes saying the HFSLPxxx.INF files were missing from C:\WINDOWS\HFSLIP. I then reverted back to a snapshot of a clean VM. Right before T-13, I got another Advanced INF Install message, but this time HFSLPGUI.INF was missing. A bit problematic, don't you think? I didn't change a single thing in my folder structure from my last successful run except to introduce rootsupd.exe and the Feb 2007 update for DirectX, readd IE7, and update KB905474. I can still post my HFSLIP.LOG file if you want, but I don't think it will help much.
