There is a patch for UT2k4 that will probably fix it, but the problem is probably caused by the DEP (data execution prevention) "feature" of XP.
As soon as I turned it off, I no longer got the crash after UT2k4, Prince of Persia, and many other games.
Here is how to do it: (You can specify specific programs to turn it off for, or turn it off for everything except core windows, which is what I did)
1. Click Start
2. Select Control Panel
3. Select System
4. Click the Advanced tab
5. In the Performance region select Settings
6. Click the Data Execute tab in the dialog box that opens
7. Select Turn on DEP for all programs and services except for those I select
8. Click Add.
9. The open dialog box will open. Browse and select your application.
10. Click Open
11. Click Apply
12. Click Ok
13. Reboot
