Why do you want to know total USD invested in ASIC mining btw?

For a few reasons.  One reason being that such a number would have a correlation to the cost to do a brute force 51% attack.  But mostly I think it is an interesting financial indicator that reflects the sentiment of the bitcoin community.  The price of a bitcoin is of course the primary measure, but I would put investment in mining hardware as a strong second.  It also just sounds cool as a talking point.  Being able to tell people 'well, if bitcoin is bullshit, better tell that to the folks who have dumped xxx millions into specialized hardware' is also a plus.

Ah, I didn't think to look at network speed over time to come up with my % ASIC power number, nice approach.  Why do you want to know total USD invested in ASIC mining btw?

I think you approach gives a good low-lower bound.  I would guess that no more than 50TH/s is due to GPUs and CPUs, just looking at where the on the graph the spike started (and that coincided with the first Avalon rigs being brought online).

I think Avalon's batch 3 pulled in about $5,000,000 alone
75 BTC x 600 units x ~$100 per btc at the time (but some were four blade units at 100 BTC)

The companies producing ASICs are all privately held.  I don't know that you could really calculate a number like that based off preorder numbers.  My suggestion for calculating a "total USD invested in ASIC mining" number would be to start backwards, looking first at total mining volume on the BTC network, ~161.5 Terahashes/s currently.  Calculate the approximate cost per Terahash/s of ASIC hardware.  I'd ballpark 1Gh/s from BFL costs about $50 --> $50,000 per Thash/s.  Next, you'll need to come up with what percent of total BTC hashrate is generated by ASIC computers at this point.  I'd go out on a limb and say 30% of the total network but this is probably way off.  Using these numbers, we find that ASICs generate 48 Thash/s of Bitcoin activity.  48.45 Th/s ASIC power * ~$50,000perTh gives us $2,422,500 in revenues.  The real number is much higher obviously, but that's my attempt to help you out.

Does anyone know, between all the ASIC companies, how much USD money has been spent on pre-orders and mining equipment?  And invested in ASIC miner shares?

Looking for a 'total invested in mining' number.
