This sounds like an incompatible driver problem to me.
You could check the SP2 setup log files in your windows directory to see if you can find the problem driver.
these log files are:
Setupapi.log
Svcpack.log
Spununst.log

Also are you installing any other programs before you try the sp2?
If so you could try to see if there is a software compatibility problem.

Two possible issues here.

How much space is free on your hard drive? I'm just guessing but I'll bet you need about 2 gig for the update

Also right click on My Computer and under General in System Properties, there is a long number in three segments, does the middle segment have the value 640?
