, I think I've found a problem with the installer. I noticed the keylayout file was getting deleted during the cleanup phase of the install but never copied back. I just tested without l2m being enabled but that may contribute to some problems.
I think it's line 56 actually that's deleting the file after copying it:
This was on my updated kernel that used the Bulletproof 9.1 installer and this file missing seems to be bad news for GPE.
EDIT: removing that line fixes the problem.
