:BTX problems probably. If you can go further, kernel will just ignore 
:things over 4gigs.

    I'm not planning on adding PAE for 32 bit kernels, but we certainly
    are planning to do a 64 bit port (aka opteron/amd64) and that will
    of course not have any of the limitations of a 32 bit address space.

    It's going to be at least ~6 months, though, at a guess.  I am doing
    the VFS work first.
