SILO/TILO currently has only gzip decompressor, so kernel has to be
compressed with gzip. But for initramfs you can use xz, as the kernel
does decompression. And with modular kernel most of the code goes into
initramfs.

10MB shouldn't be an issue - I have made a simple (non-Debian) netinstall
image for my Ultrasparcs and with 4.10 kernel, glibc 2.25, ssh and other
tools and the size is less than 5 MB.
