QEMU and Win2000 Pro SP4

[bsdzz]

When running Windows 2000 Pro inside QEMU, applying Service Pack 4 fails 
with a generic error.  I tried installing from the web and downloading 
the file locally.  I also tried SP3, which rendered my Win2000 
virtual-machine un-bootable (well it booted, but Windows wouldn't 
load).  I googled around the web, and this problem seemed to exist about 
a year ago, but I didn't see any fixes for it. I'm using FreeBSD 
5.3-Release.

Anyone succeed in applying SP4 to a Win2k Pro machine in QEMU?

thx
