I got a call from Wells Fargo because I had been using my personal account to buy bitcoins from Coinbase. They knew Coinbase was affiliated with Bitcoin, and then asked me if I was buying bitcoins for business or personal use.
It could be that Wells Fargo is more alert than other banks because of the Bitfloor incident, but it's still a trend to keep an eye on.
I opened business checking accounts with a couple major banks just to use exclusively for bitcoin buying/selling because of the volume of transactions. I'm hoping I won't run into any problems.
I think you should be fine.
