Real good question...I highly doubt it's possible at this point. If it's bricked, it's bricked. Shame they're not like Motorola devices for that, where you can just fire up RSD lite and just sbf it to restore everything to an out-of-box state. Unless you can get into the system, code in a backup bootloader/boot menu of sorts, akin to HBoot (I suppose it's possible with some knowledge of gnome terminal and/or xterm, after getting into the touchpad as superuser via command prompt or gnome terminal) that only boots when you hold a specific button combination. In theory, this is all possible.
