OK - attaching in .tgz as they'd probably cross lkml size limits:

[root@duff ~]# tar tvzf logs.tgz
-rw-r--r-- root/root 54172 2011-03-24 10:14 dmesg-2638git14.out
-rw-r--r-- root/root 51464 2011-03-24 10:23 dmesg-2638git2.out
-rw-r--r-- root/root 106118 2011-03-24 10:15 Xorg.0.log-2638git14
-rw-r--r-- root/root 107744 2011-03-24 10:23 Xorg.0.log-2638git2

thanks,
