FoxitSoftware.com has released a x64 (64bit) pdf ifilter! This means that we no longer need to rely on Adobe to make one for us. The ifilter from Foxitsoftware is currently free (hopefully it remains that way)
It can be downloaded at: http://www.foxitsoftware.com/pdf/others/ifilter/
What you can do:
1. Submit a request for enhancement
You can request a product enhancement on adobe's site at: http://www.adobe.com/support/feature.html
2. Give them a call and ask for it!
