linux reported stepping VS intel stepping

ok, forgive me if this has already been answered, but i ran a few searches and came up with nothing usable....

i currently have a p4 xeon system, with a dual-capable motherboard, but only one cpu installed. i would like to upgrade to dual, but i know the stepping has to match. when i use cpuid or cat /proc/cpuinfo, i see that my stepping is reported as "9" but intel lists their stepping like "M0" "D1" or "C1" how do I know what processor to order with the names not matching? also, i can't seem to find anywhere without rebooting whether i am on a 400 or 533 bus...

here is my cpuid output:
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 2
model name      : Intel(R) Xeon(TM) CPU 2.80GHz
stepping        : 9
cpu MHz         : 2790.839
cache size      : 512 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid
bogomips        : 5570.56
so basically, i need to know what to order from intel, so i only have to tear the machine apart once, and it will run right when i turn it back on...

Pull out the other CPU and check it on there.

i was hoping not to hear that. =)

pulling a production system offline is never fun, then i will only have to do it again after i receive a new processor... plus if i pull the heatsink off of the one in there, i'll have to clean the die to read it, then remount again with proper thermal pasting and such... ugh.
