Could you please mail me the full logfile, and the dump file (if possible, compressed as zip), to
carfesh@gmx.net?
I can then take a closer look into why it crashes in a debugger. Does it show no text between information retrieved from hardware detection: and the next line, or did you shorten the file?
It sounds like the CPU detection code may cause issues with the CPU model you use; that would be odd, as that code wasn't changed between 0.4 and 0.5.
