Yes, I belive the differences are from changes made to the 2.6 /proc
output.

My platform string has 4M also, but as you saw there is additional info
below that.  I think it is just a 2.6 thing.

I think 2.6 changed the bogomips calculation slightly.

I don't know what that even means in either case.

It is the "white box" version of the 1200.  Basically big and white, it
has the canister based hot-swap SCSI bays on the right.

I updated my SRM to the latest that was available when I got the machine
back in 2001.  I haven't touched it since then.

My dmesg:
