IIRC, 2.4 also had 0x400000 as the default load address, though maybe 
those kernels were small enough that they managed to fit.

The kernel I tested on the board goes to 0x210d84, and that's without 
any initramfs...  Sure, it's going to be tight, but it's not completely 
out of the question.

It solves the problem of not tying up over 1/4 of the board's RAM for 
what AFAICT is a not-very-frequently used feature (Linux doesn't use it, 
at least).  It solves the problem of not being able to load a current 
Linux kernel on this board.  The user can always re-enable bzip2 support 
if they really need it.
