Hi Johnny,

Many thanks - your suggested fix of a new kernel works perfectly! My Opterons 
are happy once more :)

Also - thanks Joshua for your advice: 
I last tried x86_64 with Whitebox 3, and had many problems with VMD, 
InsightII, Xeasy and MolMol - I'll have a go at 64bit again soon - has your 
64bit experience been painless ? 


Problem was:
>Centos 4.2 i386 version caused smp Opteron workstations with Nvidia graphics 
> cards to, nine times out of ten, hang when they try to re-load 
> X...  and just sitting  there with the Caps and Scroll lock LED's 
> flashing. only way out is the reset button.
