Thanks for the link. Seems this was not available when I searched for a
list of vulnerable CPUs.

I'm not sure about Xeon W5590, it is on the list but the spectre poc
does not read anything.

For meltdown, somewhere in the news I read that all Intel CPUs since
1995 are vulnerable, which is rubbish.
The paper says Intel CPUs since 2010.

I tried different approaches to get meltdown working on Xeon E5420 and
W5590 (launched Q3/2009) ... just nothing.

So I am really happy that my 10 HP Proliant DL360 G5 are still safe.
At least for me, a lot of panic for nothing.
