XB6 Capping Bridged Mode at 650mbit, Can I get help?

[DreamWraithD6]

EDIT:
this can be deleted, comcast ecs contacted me
Any way to get an XB7 stat, or have comcast let me use my own modem until they fix the XB6 Gateway Bridge Mode problem?

See below for a sampling, there are tons and tons of threads on the subject all over the place. One person on comcast forums was able to work over a month with executive support to get an XB7 sent out to them.

The comcast modem is capping me at 650 in bridge mode and so i am not getting the speeds I am paying for.
