The problem is that uname will report what the operating systems is, not
what the hardware is. This is what I get when I run a 32bit rhel3as on
a 64bit blade:
[root at xxxxxxx root]# uname -a
Linux xxxxxxx 2.4.21-40.ELsmp #1 SMP Thu Feb 2 22:22:39 EST 2006 i686 i686 i386 GNU/Linux
[root at xxxxxxx root]# dmidecode | grep Product
Product Name: ProLiant BL20p G
[root at xxxxxxx root]# lspci -v | grep 64-bit

I had hoped that some of the CPU flags would identify what I was looking
for, but sadly I know too little about the subject. It would be nice to
have a tool that can identify this without any doubt.
Kind regards,
