pergaps I've found it, grepping the source:

on pcchips787.config I read:


#
# these actions put the pcx image file on the front of the bios.
# the image size is placed in the first 4 bytes then the pcx file
# important that ROM_IMAGE_SIZE be set to 128K or larger.
# The logo file is called linuxbioslogo.pcx and should be copied to the 
build directory
#
addaction linuxbios.rom dd if=$(TOP)/src/pc80/linuxbioslogo.pcx 
of=linuxbios.rom bs=1 seek=4 conv=notrunc;
addaction linuxbios.rom perl -e '@a=stat 
"$(TOP)/src/pc80/linuxbioslogo.pcx";$$a=pack("L",$$a[7]); print $$a' | 
dd of=l
inuxbios.rom bs=1 conv=notrunc



are there particular restrictions on the image properties? width/height, 
bit depth...?
