After finding a clean install of 5.9.7 for Alpha fails I
reinstalled 5.2. Upon this clean install of 5.2 in tried an
upgrade to 5.9.7 by FTP. Near the end, as it updates
XFree86-3.3.2..., it bombs with a signal 11. This is
repeatable. The Alpha in question is an XL266.
Fixed in 6.0 final (alpha isn't out yet)
