You have compiled everything in, haven't you?
Current SILO is not able to load images larger than 2.5M-16384.
So, for now, modularize your kernel a bit. I will in the mean time try to
think how to make SILO able to handle larger sizes (but there will probably
be a limitation 3M-100K even then). The problem is SILO is statically linked
to 0x280000 address, which is caused by old Suns where they guarantee only
3M of contiguous mapped memory.

Cheers,
