SunPCi 3.2 problem

[Lars Hecking]

 I have encountered a major problem with SunPCi 3.2, and was wondering
 whether anyone has experienced similar issues.

 We deploy SunPCi the follwing way:

 - an initial W2k image is created, and W2k installed on it
 - shared networking is configured as described in the user's guide
 - all required patches and applications are added
 - on the final image, we run sysprep; sysprep is a tool provided
   by MS to strip host and network specific information from a
   host (a bit like /usr/sbin/sys-unconfig)
 - the sysprep'd image can now be copied to other machines, vastly
   reducing the overall setup time

 The problem we see now is related to sysprep. When a sysprep'd image
 is booted, it prompts for host and network related information to be
 entered, and then W2k reboots to finalise the setup. However, after
 this final reboot, and only then, the display is completely garbled.
 Has anyone seen this before?
