Thanks for your info!
Now it's clear, since in d-i, file
build/pkg-lists/netboot/network-console/armel/orion5x.cfg

oldsys-preseed
# sata and ext2/ext3 modules are needed by oldsys-preseed to read the disk
# -> disable due to size problems

I think maybe it's necessary to split "orion5x" as:
- orion5x with serial console support, which keeps current config, so
as kuroboxpro can be supported
- orion5x without serial console support, re-enable sata and ext4, but
disable jffs2 and micro-evtd

What's your idea?
