Apple has released an update to the early 2011 iMac EFI firmware. The new update is labeled version 1.7 and it is available via software update.
The update addresses the following issues:
This update enables Lion Recovery from an Internet connection and includes fixes that resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on iMac (early 2011) models.

I’ll be the first to admit that I’m surprised that Apple enabled Lion Internet Recovery on the iMac I purchased in June. I thought they’d hold out and only offer it on a refreshed model as an incentive to upgrade our iMacs.
