= I find it very strange that the kernel is being linked to start at
= 0xc0010000.  It's not your average machine that has this much physical
= memory.

Linux on i386 is also relocated to around 3Gb.  In both cases,
Linux is physically loaded near 0Gb, and then physical memory is
virtually mapped to show up starting at 3Gb.  Until the VM is
enabled you're right, using those 3Gb addresses won't work in a
debugger.

= Comments?

Sure, that's the way it's done in Linux 2.2.x right now and it
is the kernel machine-independent code assumes that scheme or a
simliar one is in effect so we can't really change it.  I don't
know what 2.3 has done.
