I know the Dell 2850 can support a 64-bit processor: My question is, do all 2850 CPU's support 64-bit?  I have a 33 production 2850's running 32-bit Linux with Oracle 9i and want to upgrade to 64-bit Linux with Oracle 10g.  I can see from /proc/cpuinfo that "lm" long messages are supported (which should allow it to run 64-bit) but there are other indications that the server is only capable of 32-bit.  I need to understand if a 2850 is ALWAYS capable of 64-bit support or SOMETIMES?
