Was it about the same as the latest CPU-miner?  CPU-Miner seems to get around 1~2 MH/S per core.

I am wondering this, because the average network hashing rate for the first year of bitcoin's existence was around 5MHash/S.  That would mean there were on average, only 5 nodes in the bitcoin network the first year.

Also, when did the client start supporting external miners?

check out:

The difficulty stayed at 1 the whole first year (2009), because there were only a handful of nodes on the network.  In other words, at 2 MH/Sec, you could have mined almost 700,000 bitcoins the first year with just a middle of the road dual-core CPU.

Which would be worth around $10 million now.

Read it and weep

UFAsoft's CPU miner used to give me 5.1 mh/s at E2140.

I know that the external miners have good performance.  I was more wondering about the native client performance.  The original didn't allow external miners to connect, right?

Client version 0.3.9 gave around 3 MHash/s on a 3.2GHz quad-core i5. Later versions pushed this up to around 5 MHash/s due to the cumulative effect of a number of tweaks.

The original didn't allow external miners to connect, right?

Correct, but from around the time that poclbm was released there was a patch floating around so that you could recompile your client to include the getwork function so that external miners could connect.
