It looks like it's between 2.4 and 2.6 MB depending on
the source.

I found a 2 year old patch to silo that loads the kernel
above 4 MB like sparc64 but the sparc32 kernel is not
relocatable. It loads fine but then tries to move it down
low where it wants to be and fails because there isn't
enough space.

SILO Version 1.4.14
boot:
Allocated 64 Megs of memory at 0x3FFFC000 for kernel
Uncompressing image...
Your kernel cannot fit into the memory destination. This
can be resolved by recompiling the kernel with more devices
built as modules, or upgrading your kernel to one that
supports being loaded to higher memory areas (currently
2.6.3+ or 2.4.26+).
boot:

I'm looking at head_32.S and head_64.s to try and figure
out what's involved in making sparc32 relocatable but I'm
not sure what to look for. Any hints?
