*at() can not be MFCed as it would change the native VFS ABI (Roman  
implemented the FreeBSD side of *at() calls to be able to emulate the  
linux *at() calls).

As you noticed, this is a major point in 2.6.16 emulation.

Another thing which is in current but AFAIK not in stable is the brand  
detection stuff, but I think this is not so critical to have in  
RELENG_7.

Other changes may or may not be MFCable, but AFAIK nobody took the  
time to compare RELENG_7 with CURRENT and had a careful look at the  
differences. Anyway, as *at is a major part and can not be MFCed,  
2.6.16 + linux base f8 is not a supported combination in RELENG_7. If  
it works for you feel lucky, if it does not work for you... that's bad  
luck.

Bye,
Alexander.
