I am having a very simiar problem.
I downloaded the full SP1 install and began upgrading my Sony AR series laptop- 4GB Ram, 300+ GB Hard Drive, Vista Ultimate
I let it do its thing and came back to a black dos screen displaying:
!! 0x0190036 !! 1996/72455 (gameux.dll)
It's kind of flashing, like the screen is redrawing it over and over again but always in the same place.
I rebooted the machine normally and it appears to go through dozens (maybe hundreds?) of OS files this way and then always gets stuck at the same point.
It told me Windowss Failed to Start and gave me the recommended option of "Launch Startup Repair" which I did (and removed all USB devices so nothing is connected that doesn't absolutely have to be)
I get the "Startup Repair is checking your system for problems..." window and it does its thing, reboots, and comes to the same problem.
I tried starting as Last Know Good Configuration - same problem.
I tried starting in Safe Mode- the computer just hangs after loading some file (which I didn't write down but isn't the same as above)
I did the restore point to just before I began the SP1 install and am back online... no idea why it happened or if it will again.
