Log Message:
Found the issue with the kinetic bootloader.

Seems that we assume that the dram blocks are sorted, and that the first/lowest 
address is also where the kernel is.

If the above is not true, then we're on a kinetic (probably should make a 
better way to indicate this)  So search for all dram blocks < with starting 
addr lower than the first block and remove them.

Currently there's minimal performance gain (which is odd as the SDRAM is meant 
to be faster, I'm wondering if we need to prod some hidden registers to set 
timing information.

Note that I still get 16MB/s compared with 7MB/s on RiscStation and 93MB/s on 
my cats.  I'm thinking that something else is seriously nasty on acorn32.
