I am generally interested and will probably look at it between Christmas an= d=20 the New Year - unless Damien wants to look at it himself. The current sche= me=20 of loading the firmware is disfunctional with a WITNESS enabled kernel (too= =20 much "sleep while holding mutex") and needs to be fixed anyway. Is this work in perforce?
