Hi Sean,

Thanks for the patch, and thanks for re-pushing it :)
This is to inform you that the BIOS update referenced :
Version: SC24 BIOS V1.01
Release Date: 01/11/2013

Seems to fix "my" tty detection problem on 3.7 (tested on a 3.7.6 
Fedora kernel, with success).
I don't think the patch will hurt anyway - I believe it still will 
prevent other users from a regression.
I also confirm that the patched 3.8.0 detects its ttys fine on a 
BIOS-updated system.

Regards,

Vincent
