Firefall does the chat the same way, and I hate it there too.
Here's the thing...
Playstation 2 and 3 support mouse and keyboard. There are after market keyboards, but most USB and Bluetooth keyboards "just work" when paired to the PS3 (PS2 is USB only).
For Xbox:

DC Universe has chat tabs.
It has an option to lock the chat on.
And the keyboard/mouse on the PS3 version works, identically to the PC version.
On the Sony keyboard, there are three keys right above select/start. One is for quick chat, one is for mouse, and I forget what the heck the other one does. While it's in mouse mode, the keys don't work and the entire surface is touch sensitive, so you use it like a track pad.
