Reserve bss space for modules

[Arnaud Vrac]

I am developping a kernel that is split in modules for my studies, using 
GRUB to boot it and load modules in memory. GRUB allocates space for the 
 sections in the kernel ELF, and also reserves space for the bss 
symbols. Is it possible to tell GRUB to reserve space for the bss 
symbols, for a module ?

I did not find any information relating to that point, and as of now, 
all the modules i load are concateneted in memory (page aligned), 
leaving no space for the bss symbols. Do i really have to parse the elf 
headers and allocate the space myself ?

Thanks
