:> when i wanted to debug this, another issue popped up:
:> 2. kgdb doesn't work anymore (with /dev/mem):  it tries to read=20
:> CPU_prvdata but fails reading from 0xff800000.  this somehow worked=20
:> before, and it works in 1.4-release/gdb -k.  so something in the=20
:> kernel must have changed since.  because of this i couldn't debug 1)
:this is still current, tho.

    I've encountered this too.  I'll try to get it fixed today.  I think
    it is due to the bounds check code in /dev/mem.
